Case Trimmer Pilot

[O.S.O.K.]

Trying to put all the pieces together so I can finally start reloading Grendel ammo.

Quick question: Should I just use the same size pilot as on a 7.62x39 case?

[Von Gruff]

The pilot goes into the mouth of the cartridge so No, the 7.62x39 case will use a 7.62 pilot while the Grendel will need a .264 pilot.

Dang, those seem to be hard to find!

Perhaps you're confusing the case holder with the pilot, since both cases use similar sized holders. The pilots, on the other hand, will be significantly different, depending on the type of trimmer. 6.5 mm case mouths will not fit over the 7.62 pilot, whereas the reverse would be true. I personally would look for as close fitting pilot as possible. A 6mm pilot could do in a pinch, but you're risking introducing unevenness of the case mouth, should the case wander around the pilot. (That depends again, on the style of trimmer you use.)

A 264 pilot wasn't locally available when I wanted one so for my imediate needs I used a 270 pilot and spun it in a drill dressing it down using 350 W&D till it fit inside a fired case then used 400 then 600 grit to fine it down till it was a nice fit in a sized case. Simple to do.

I'd contact the company that makes your trimmer, or check their website, to see if they have the .264 pilot (they should). I have the Lyman trimmer and had to order that piece separately.
