302w 83 Posted June 3, 2016 What do you guys do for gas checks? Old supply? New supply? If so, where? Home brew? I need some 30 cals for my M1. EBay has them cheap. Quote Share this post Link to post Share on other sites

Might be able to forgo the gas check. Otherwise there's a healthy supply of them on cast boolits. Sent from my Z812 using Tapatalk Quote Share this post Link to post Share on other sites
noylj 5 Posted June 4, 2016 If eBay has them cheap, you are set. If velocity is under about 1800 fps, you shouldn't need a gas check. I hear good and bad about making gas checks from Al cans. Quote Share this post Link to post Share on other sites
