.31 and .32 cal Gas Checks

[bpimwheel]

Will .30 caliber gas checks fit on .31 or .32 caliber rifle bullets.
I need GCs for my 1909 Argentine in 7.65x53 (.313) and .32 Win Spl
Ive seen .30 for sale but not seen .31 or .32 so not sure.
Thanks for any help

They will fit but a better fit would be 8mm or 32cal gas checks, I use 8mm on my 303 through a 0.316" sizer with good results.

i use 8mm checks on my 32 win... i bought them here... it was my primary meat getter last year.

Thanks Bad *** and Marko, I didn't think of the 8mm for 32.
But what about the .31 (7.65x53 Argy) Seems 8mm might be to large.
Any help there?

The diameter of the bullet isn't the whole issue with .30 and .32 caliber GC bullets, it's the GC shank on the bullets. A fat shank can be a real PITA to deal with. One of my big name brass molds casts a .293" shank and I had to expand the GC's to fit. Now one good thing about that is they are really on there after sizing.

.284" seems to be what's standard for the .30's and .32's GC shank, but I've only got one .32 GC mold so take it FWIW. When I started with this particular mold, I seem to remember the 8mm GC was too big, but I will go back and look.

Your .313 boolit does indeed use the 30 cal gas check.

The two bullets I like best for my 7.65 x 53 and also my SMLE are the 314-299 and 314-135. Both have shanks that work best with 30 cal gas checks.

The 314299 is what I'm using for my 1891 & 1909 Argy.
Not sure what mold for the 32 Win Spl yet.

I had a NOE 316299 that dropped fatter than 316, and the boolit would accept a standard Hornady 30 cal GC.
