The Lyman E-Zee Pilot Case Trimmer – .300 AAC Blackout (Lyman part no. 7821914) is a caliber-specific case trimmer pilot built to bring .300 AAC Blackout brass to a precise, uniform trim-to-length dimension. Lyman built this pilot to hold up to repeated use on the reloading bench. It works equally well by hand or chucked into a power drill, making it just as useful for a handful of cases as for a full batch. Reloaders who shoot .300 AAC Blackout and want consistent case length from round to round will get the most out of this pilot.
Key Specifications
- This pilot is sized specifically for .300 AAC Blackout cases, so it delivers a precise trim-to-length cut without adapting a generic pilot to the wrong case dimensions.
- A case locking device is included to hold the case square and steady during the cut.
- A dedicated cutter head is included so the trimmer is ready to use right out of the box.
- It runs by hand or with a power drill attachment (both included), so it scales from a few cases to a full batch.
Frequently Asked Questions
Will this pilot work on other calibers besides .300 AAC Blackout? No. This pilot is sized specifically for .300 AAC Blackout cases, so a different caliber requires its own matching E-Zee Pilot.
Can I use this with a power drill instead of trimming by hand? Yes. The kit includes both the hand and power trimming adapters, so it can be run either way.
What comes in the box? The pilot ships with a case locking device, cutter, trim-to-length pilot, and both the hand and power trimming adapters.
