I’m sure I know the answer to this, but I’m slightly confused, I went to check some 45-70 projectiles last night with Hornady 45 cal gas checks and the check didn’t snap on like normal. So I put it in the sizer and pushe it down to crimp the check on and size the bullet and the check fell off of one and was barely holding on the other. So I’m wandering if it’s a stupid rookie mistake and o dolidnt go deep enough in the Redding die or is the check shank of the bullet is undersize. Anyone else had this issue?

IME, Lyman GC shanks and Hornady checks usually have the opposite problem--shank too thick for Hornady checks. Lyman checks were thinner than Hornadys in earlier times, and Lyman checks didn't crimp on like Hornadys do. You don't mention which mould maker is involved, I sounds like the shank might be undersized for that lot of checks. I haven't noted a lot of variance in Hornady checks over the years, just the price keeps climbing.

I never used that mould, sorry it's giving you trouble. I would try a few more to be sure, if the shank is undersize you could lap it a hair, chuck a bullet is a drill, wipe a bit of compound in the shank portion of the mould, insert the bullet( gas check shank) while holding the blocks closed. Bet it wouldn't take much. I like the Clover brand compound, a small can goes a long way.
Found the issue. The checks are a hair big for the bases. Bases are .421, and checks are .425 measured several. So no biggie. @Joshua im thinking what your thinking already.
@S Mac it’s not an issue that mold casts some really nice bullets. I really like both of them. Hoping one of them shoots. I’ll either order me a custom check maker or I’ll powder them them check them.

Or you could try and find gas checks for small shanks. I have that issue with an MP 44 caliber mould. Sent it back but issue wasn't corrected............I wasn't the only one, either. The honcho that ran that group buy, did too. He turned me on the those checks. Was buying them from Sage's. They were aluminum. Last time, I was on Sage's site, they weren't listing them at all. 
That might warrant a phone call or email, when I run low.

Boy, if I was shooting a .45-70 at velocities high enough to warrant gas check use I believe I'd start wetting the bed. Maybe you'll get extra lucky if you PC and not need checks at all.
Not planning on pushing them that hard. It's a GC mold so I was going to check them. Going to try a couple things and see what I can come up with.
