If you reload your own ammo, then you certainly need a reliable case prep center. Case prep stations help you perform multiple functions to prepare your brass for the reloading press—all from one compact workstation.
They can help you trim, chamfer, and deburr your casing. You can also use them to clean primer pockets and remove military crimps. Having a motorized case prep center is far more efficient than using individual manual tools for each task, especially when processing large batches of brass.
However, not all case prep centers are created equal. Motor power, included accessories, noise levels, and durability vary significantly between models. After researching specifications, analyzing user feedback from reloading forums like Sniper’s Hide and AccurateShooter, and comparing manufacturer data, we’ve compiled this guide to help you select the right case prep center for your needs.
Overview: Case Prep Center Advantages and Disadvantages
Advantages
- Significant time savings – Experienced reloaders report processing 50+ cases (trim, chamfer, deburr, clean primer pockets) in under 15 minutes with a powered center versus hours with manual tools.
- Reduced hand fatigue – Motorized operation eliminates the repetitive stress from manual chamfering and deburring, especially important for high-volume reloaders or those with arthritis.
- Consistent results – Quality case prep centers with micrometer adjustments deliver trim lengths within ±0.001″ for precision reloaders.
- Multi-function convenience – One tool handles chamfering, deburring, primer pocket cleaning, flash hole uniforming, and in some cases, trimming.
Disadvantages
- Initial cost – Quality case prep centers range from $80-$400+, a significant investment compared to $30-50 in manual tools.
- Bench space required – Most units require permanent mounting and take up substantial workspace (some units measure 6-10″ in multiple dimensions).
- Learning curve – Each model operates differently; improper use can damage brass or create inconsistent results.
- Potential for over-processing – Forum users warn that powered tools work quickly—it’s easy to over-chamfer or over-deburr if you’re not careful.
What is a Case Prep Center?
A case prep center is a motorized workstation that allows you to prepare brass cases for reloading. Unlike individual hand tools, a prep center consolidates multiple functions—chamfering, deburring, primer pocket cleaning, and sometimes trimming—into one powered unit with multiple tool stations.
Most centers feature between 3-6 powered stations driven by an electric motor, with speeds ranging from 125-550 RPM depending on the model. They typically use standard 8-32 threaded tool attachments, meaning you can use accessories from multiple brands.
Each model has its own design, so you’ll need to carefully read the manual for your specific unit. Motor torque ratings range from approximately 9 inch-pounds on entry-level units up to 43 inch-pounds on premium centers like the Sinclair Power Center.
1. Frankford Arsenal Platinum Series Case Prep Center
The Frankford Arsenal Platinum Series Case Prep Center stands out for its compact footprint and budget-friendly price point. Measuring just 6.93 x 6.46 x 4.96 inches, it’s notably smaller than competing units, making it ideal for cramped reloading benches.
The unit features four powered tool stations operating at 200 RPM, with 8-32 threaded output shafts that accept most aftermarket case prep tools. The durable aluminum construction and hardened high-speed steel (HSS) tools are designed to stay sharp through thousands of rounds. According to one Long Range Hunting forum user, their unit has “processed approximately 10,000 rounds and shows no signs of wear.”
The kit includes an inside chamfer tool, outside deburring tool, and large/small primer pocket scrapers. Note that this is the prep-only model (1077094)—it does not include a case trimmer. The larger Case Trim & Prep System (903156) adds trimming capability but is a separate, more expensive product.
Pros
- Compact design takes minimal bench space—significantly smaller than RCBS or Lyman alternatives
- Budget-friendly entry point for motorized case prep
- 4.7 out of 5 star average rating from 20+ verified reviews
- Durable aluminum housing and HSS tools rated for thousands of rounds
- Compatible with most 8-32 threaded aftermarket accessories
Cons
- Does not include a case trimmer—trimming requires separate equipment or the more expensive Trim & Prep System
- Only four stations versus 5-6 on competing models
- Separate expansion kit required for primer pocket uniformers and military crimp removers
2. RCBS 90375 Trim Mate Case Prep Center
The RCBS 90375 Trim Mate Case Prep Center is a proven workhorse with a reputation for longevity. Forum users on Long Range Hunting report units running reliably for 14-20+ years of regular use.
The unit weighs 6.4 pounds and features five gear-driven rotating stations plus two stationary positions for case neck brushes or dry neck lube. The high-torque motor operates at 120VAC (110V for US models) and provides steady power without the excessive speed that can cause over-processing. One ExpertVoice reviewer noted it “works good for those with arthritic hands. The spindle speed is just right and not too fast with just the right torque.”
The kit includes large and small primer pocket brushes, inside chamfering and outside deburring tools, medium and small case neck brushes, and dry case neck lube. Importantly, this model does not include a case trimmer—it’s designed to pair with the RCBS Trim Pro Power Case Trimmer or similar.
Pros
- Exceptional longevity—multiple forum users report 10-20+ years of service
- RCBS customer service is highly praised; one user received a free replacement power cord even after warranty
- Seven total tool positions (5 powered, 2 stationary)
- Moderate speed reduces risk of over-chamfering or over-deburring
Cons
- Does not include a case trimmer
- Noise level is controversial—some users find it surprisingly quiet, others report it’s “very noisy”
- Forum users recommend upgrading to carbide chamfer tools as “the one it comes with sucks”
- Some users report the outside deburring tool doesn’t work well and causes finger fatigue
3. Hornady 050012 Lock-N-Load Power Case Prep Center
The Hornady 050012 Lock-N-Load Power Case Prep Center is unique among the options reviewed because it includes a built-in power case trimmer—making it a true all-in-one solution. According to multiple forum users, “It is the only one on the market that includes a built in case trimmer, along with doing all the other usual case prep functions.”
The unit can trim cases from ¾” to 3¼” in length with micrometer adjustments down to 0.001″. The vertical trimmer design and horizontal tool orientation keep brass shavings from falling into cases. Removable catch trays provide easy cleanup. The Cam-Lock™ feature secures cases in removable shell holders for precise, repeatable trimming.
One F-Class competitor on OpticsPlanet stated: “I go through about 3-4 thousand rounds a year… in my opinion there is nothing else on the market that does all the things that this machine does as well or as efficiently.”
The motor includes an in-line fuse for protection—if you try to trim more than 0.050″ too quickly, the fuse may blow to prevent motor damage.
Pros
- Only case prep center in this price range with a built-in power case trimmer
- Micrometer-adjustable trimming to 0.001″ precision
- Innovative shavings management keeps brass out of cases
- No-Risk Lifetime Warranty from Hornady
- 5.0 out of 5 star rating on multiple retail sites
Cons
- Spindle locking bolt reportedly made of soft metal—one user reported it notched within 500 pieces
- Shell holders and trimmer pilots sold separately (uses Hornady-specific accessories)
- More complex setup than prep-only units—requires mounting to bench with bolts
- Higher price point than prep-only centers
4. Lyman Case Prep Xpress 115V 7810220
The Lyman Case Prep Xpress 115V 7810220 is frequently recommended by forum users for its quiet operation, comprehensive accessory package, and mess containment. The motor operates at 125 RPM—slower than some competitors but paired with high torque for smooth, controlled operation.
The unit uses standard 8-32 threaded tools, meaning it accepts accessories from RCBS, Hornady, and other brands. One user on OzFclass forum reported: “I have had the LYMAN for around six years and can honestly say it’s one of the best additions to my reloading kit… I have prepped thousands of cases from .223 to .50 BMG.”
The included accessory package is extensive: inside deburr (VLD) tool, outside deburr tool, primer pocket uniformers (large and small), primer pocket reamers (large and small), primer pocket cleaners (large and small), case neck brushes in 25, 30, 38 and 45 caliber, mica case neck lube, removable brass shavings dump pan, and clean-up brush. This makes it one of the most complete out-of-box packages available.
Forum users consistently praise the mess containment compared to the RCBS Trim Mate, noting the Lyman “catches the mess” with its integrated dump pan.
Pros
- Exceptionally quiet operation—consistently praised as quieter than RCBS alternatives
- Most comprehensive included accessory package of any case prep center reviewed
- Integrated dump pan for shavings containment
- Multiple forum users report 6-10+ years of reliable service
- Standard 8-32 threading accepts multi-brand accessories
Cons
- Does not include a case trimmer
- Larger footprint than Frankford Arsenal—may be an issue for limited bench space

- Can struggle with military crimps even after swaging—”doesn’t remove military crimps as advertised” per one user
- 125 RPM may feel slow for high-volume production
5. Hornady Lock-n-Load Case Prep Trio
The Hornady Lock-n-Load Case Prep Trio is a budget-oriented option featuring a brushed aluminum housing and three powered tool stations. It’s designed for reloaders who want basic motorized case prep without the complexity or cost of larger systems.
The unit features a high-torque, low-speed motor and includes inside and outside chamfer/deburr tools. Additional 8-32 threaded accessories like primer pocket cleaners, reamers, and case neck brushes can be added. The compact three-station design fits easily on crowded benches and works with 110V or 220V power. Made in the U.S.A.
However, this model has received significant criticism regarding durability. Multiple users on Cast Boolits forum reported the internal plastic gears failing after only 100-200 cases. One user found “the most flimsy plastic gears inside, broken” after the unit stopped working. Hornady customer service has acknowledged “some of the original units had this problem with crappy CHINESE gears” and offers free replacement gears, even for out-of-warranty units.
Pros
- Most affordable motorized case prep option in the Hornady lineup
- Compact three-station design fits any reloading bench
- Brushed aluminum housing for durability
- Compatible with 8-32 threaded accessories from any brand
- Hornady’s customer service provides free replacement gears even out of warranty
Cons
- Significant durability concerns—multiple users report plastic gears failing within 100-500 rounds processed
- Lacks sufficient grip on bottom—slides during use, requiring you to hold it steady
- Only three stations versus 4-6 on competing models

- Outside reamer may develop grinding noise; users recommend greasing internal gears periodically
6. RCBS Universal Case Prep Center
The RCBS Universal Case Prep Center is RCBS’s premium offering, featuring both a built-in power trimmer and case prep stations. The 24-VDC motor delivers up to 360 RPM with 9 inch-pounds of torque, and users can adjust the output shaft RPM to their preferences.
The unit features six stations total: four at up to 360 RPM and two at up to 550 RPM for faster processing. The standout feature is the spring-loaded feed system for hands-free trimming—a single ambidextrous lever loads and unloads cases then disengages them from the cutter.
The Universal shell holder accommodates cases with rim diameters from 0.250″ to 0.625″ and overall lengths from 0.720″ to 3.375″—no collets required. Micrometer adjustment enables fast, precise cut length changes.
According to an Amazon reviewer: “Fixed cutterhead, Universal Case holder and the design that pulls the case spring loaded into the cutterhead is over the top. This product is the best designed and fastest trimmer that’s on the market today!”
Note: According to OpticsPlanet, this model has been discontinued by RCBS. Some retailers may still have remaining stock.
Pros
- Includes built-in power trimmer with micrometer adjustment
- Universal shell holder eliminates need for caliber-specific collets
- Six stations with variable speeds (up to 550 RPM on two stations)

7. Sinclair Power Center
The Sinclair Power Center (available through Brownells) is a premium option favored by precision reloaders. The motor operates at 200 RPM with an impressive 43 inch-pounds of torque—significantly more powerful than entry and mid-level units.
According to Rifleshooter.com’s review, “The Sinclair Power Center is a significant upgrade over the ubiquitous RCBS Trim Mate case prep center. The greater torque, horizontal tool orientation and higher RPM are welcomed improvements.”
The 3/8″ capacity keyless chuck accepts nearly every case prep tool offered, regardless of brand. The motor and gearhead are completely enclosed in a vented housing with no exposed capacitors or wires. The top-mounted heavy-duty on/off switch is ergonomically positioned for neck turning operations that require frequent stops.
The 6-foot heavy-duty power cord with grounded plug adds safety and convenience. Common uses include primer pocket uniforming, flash hole deburring, inside case neck cleaning, chamfering and deburring, and neck turning.
Pros
- Highest torque rating of any unit reviewed (43 inch-pounds)
- Keyless 3/8″ chuck accepts virtually any case prep tool
- Fully enclosed motor and gearhead for safety

Buyer’s Guide: How to Choose the Right Case Prep Center
Key Factors to Consider
- Volume of reloading: If you process 200+ cases at a time, invest in a unit with higher torque and more stations. For occasional reloaders doing small batches, a basic three-station unit may suffice. As one forum user noted, “For short run reloaders who are doing small batches (200 or less), I can’t recommend a bulky prep center… For those looking at an ice cream pail of brass, this thing is going to be your best friend.”
- Trimming needs: Decide whether you need integrated trimming. The Hornady Lock-N-Load 050012 and RCBS Universal include built-in trimmers. Other units require a separate trimmer, which may be preferable if you want higher-end trimming precision (like a Giraud or Henderson).
- Noise tolerance: The Lyman Case Prep Xpress is consistently praised as the quietest option. RCBS units receive mixed reviews on noise—some find them quiet, others report them as loud.
- Bench space: The Frankford Arsenal Platinum at 6.93 x 6.46 x 4.96 inches is the most compact. The Lyman and RCBS Universal require significantly more space.
- Accessory compatibility: Most units use standard 8-32 threaded tools, meaning you can mix accessories from different brands. The Hornady Lock-N-Load 050012 uses proprietary Hornady shell holders and pilots.
- Durability: The RCBS Trim Mate has the best long-term reliability reputation, with users reporting 10-20+ years of service. The Hornady Case Prep Trio has documented issues with plastic gear failures.
Who Should NOT Buy a Case Prep Center
- Occasional reloaders processing fewer than 50-100 cases at a time – Manual tools may be more cost-effective
- Extreme precision shooters – Some forum users feel powered prep centers are “more of a toy than a serious machine” for benchrest-level work, preferring hand tools or premium single-purpose equipment
- Those with very limited budgets – A $100+ prep center plus accessories may not make sense when $30-50 in quality hand tools can accomplish the same tasks
FAQ: Case Prep Center Questions
Do I need a case prep center for reloading?
No, but it significantly speeds up the process. You can perform all case prep tasks with manual tools, but a motorized center is recommended if you regularly process more than 100-200 cases at a time or have hand fatigue issues.
Can I use accessories from different brands?
Most case prep centers use standard 8-32 threaded tool attachments, meaning RCBS tools work on Lyman centers and vice versa. The exception is the Hornady Lock-N-Load 050012, which uses Hornady-specific shell holders and trimmer pilots.
Why do some centers not include a trimmer?
Many reloaders prefer dedicated case trimmers for precision work. Separating trimming from prep allows you to invest in higher-end trimmers (like Giraud, Henderson, or WFT) while still using a basic prep center for chamfering, deburring, and pocket work.
How long do case prep centers last?
Quality units like the RCBS Trim Mate and Lyman Case Prep Xpress commonly last 10-20+ years with regular use. Budget options like the Hornady Case Prep Trio have documented durability issues and may fail much sooner.
Are carbide tools worth the upgrade?
Yes. Multiple forum users recommend upgrading to carbide chamfer tools regardless of which prep center you choose. The steel tools included with most units wear out after a few hundred rounds, while carbide tools last significantly longer.
Conclusion
Selecting the right case prep center depends on your volume, budget, and specific needs:
- Best Overall Value: The Lyman Case Prep Xpress 115V offers the most complete out-of-box package with quiet operation, excellent mess containment, and proven long-term reliability. It’s particularly well-suited for high-volume reloaders processing large batches of brass.
- Best All-in-One Solution: The Hornady Lock-N-Load Power Case Prep Center (050012) is the only unit that integrates a micrometer-adjustable power trimmer with full case prep capabilities—ideal if you want one tool to handle everything.
- Best Budget Option: The Frankford Arsenal Platinum Series delivers solid performance in the most compact package at the lowest price point. Perfect for those with limited bench space or budget.
- Best for Precision Work: The Sinclair Power Center with its 43 inch-pound torque rating and keyless chuck is the choice for serious precision reloaders doing neck turning and demanding case prep work.
Whichever unit you choose, remember that “a case prep center at the end of the day is a sufficiently powerful electric motor in a housing,” as one forum user noted. Any of the reputable brands—RCBS, Hornady, Lyman, Frankford Arsenal—will put out a quality product backed by solid customer service. The key is matching the features to your specific reloading workflow.
