Hey all, I have a novice question. I've been handloading about three and a half years and i'm very comfortable loading straight walled cases , no concern with that at all. I have loaded for my marlin 336 (30-30), but not extensively - about 50 rounds or so, mostly as load development and that has gone well. Last winter i got a deal i couldn't pass up on a winchester 94 basically new in box with a few hundred factory rounds very cheap. My question is, how to properly size my brass so that both rifles can use the same ammo without over working it / should i just full length size all 30-30 brass or how can i determine which has the shorter chamber and would that be the correct way to ensure function if i dont want to keep ammo seperated specifically for each rifle. i try to size the minimal amount required , cartridges i've produced for the 336 chamber and cycle fine in the 94 but i have not loaded any brass fired from the 94 and tried to load it in the 336 but do have some fired cases from the winchester and i'm ready to get to work on them just want to do it properly without over working the brass needlessly and pushing the shoulder back further than i need to. I have a feeling that i'm over thinking this, but i figured i bounce it off you guys so i can stop spinning my gears on it. Thanks!
