I read somewhere that annealing the gas check helps to stabilize the flight of the bullet? Thanks for your reply, Hank

As a side note for those that are not familiar with the rules.
Section 2.01: Bullets
Bullets must be of lead or lead alloy with no metallic gas checks, half jackets or other metallic jackets. These
may be loaded from either the muzzle or the breech and may be paper patched at the shooter’s option.

Hank, I did it one time, since I'd been told "it's the thing to do". Used a frying pan to cook up half a box of .32 cal checks. Then, I had to clean up the mess with good ol' Lemishine because they were black and ugly. (I think they had some forming lube or something on them). Anyhow, they are softer than the rest of the box, but don't shoot a bit better than the others from the same box. I just mixed them back up together and now and then shoot twenty or so. Take me the next three lives to shoot both boxes I own.
