Hi All,

I have purchased a mold caliber .502 in Australia, this mold is gas checked, I have purchased right gas checks for this mold at the same company but price if high.

Do you know a frim or a guy who made this particular gas check?

Many thanks for your input.

Bullet Swaging Supply makes a couple of 500/50 cal checks. One for the 500 S&W that takes a shank of about 0.4585". The other for the .510 bores taking a shank about 0.4685". (318) 387 7257. The price is $34 per thousand. It is not cheap to shoot the 50's

MTN,

All big bore calibers are expensive to shoot but so great that worth
