Gas check sizes

[LonesomePigeon]

I am going to start casting bullets and reloading for a Winchester Model 94 in .32 Win Spec and an Argentine Mauser in 7.65 x 53. I have the Lyman Cast Bullet Handbook 4th Edition and I see that these take gas check bullets but I don't see which sizes. What size or sizes of gas checks should I use for these two calibers?

Sounds interesting. I wouldn't have a clue about the 7.65X53, but wouldn't the 32 Special just take 32 caliber gas checks?
It's been so long since I cast bullets, I can't even remember where my gas check stash is. The only box I was able to find was a box of Hdy 44 caliber gas checks that I obviously used for the 44 Mag bullets I used to cast.
At any rate, I'm thinking you might be able to call the people who made your bullet molds. They should be able to tell you what size gas checks to use.
BTW, I remember always using Hornady gas checks even though I have mostly Lyman molds. I like having the gas checks crimped on - personal preference.

the 32 win spec would use a 0.323 gas check and I'm not 100% sure on the 7.65 x 53 Mauser, but it's a .312 bore diameter, so I would assume that it takes the 30 Caliber Gas checks. You want to confirm that one though.
