RCBS 90366 Trim Pro-2 Manual Case Trimmer with Shield for .22-.45 Caliber Reloading

The RCBS Trim Pro-2 manual case trimmer is a precision reloading tool built for shooters who demand consistent case length across their loads. If you're prepping brass for handloading—whether you're working with common rifle rounds or specialized cartridges—this trimmer combines adjustability and reliability in a compact bench-mounted platform. The spring-loaded universal shell holder keeps cases centered and secure during trimming, eliminating the guesswork and delivering the .001" accuracy that separates good handloads from great ones.

What sets the Trim Pro-2 apart is its dual-adjustment system: coarse trim length adjustments for quick setup, and a fine adjustment bushing with .001" micrometer markings for dial-in precision. The shell holder's spring-loaded design accommodates case head diameters from .250" to .625", which translates to real versatility—you're covered from small rifle rounds like the 5.7x28mm all the way up to magnum long-range cartridges like the .338 Lapua Magnum. The included shield protects your hands from the cutter and loose brass shavings.

The kit ships with nine pilots (.22, .24, .25, .27, .28, .30, .35, .44, .45 caliber), so most common reloading projects are ready to go out of the box. Additional pilots are available separately if you need coverage beyond this range. This is a manual trimmer, so it rewards patience and attention—no motorized press, just straightforward mechanical control over a critical part of the reloading process.
