I am posting as a sanity check. I gather from my cursory research that gas checks are only needed at velocities (and levels of heat) which cause lead alloys to deform. In handguns, that would include the serious loads for the magnums and .45 Colt +p or "Ruger only" range. In semi-autos, the 10mm is the prime candidate other than the Hollywood guns.
So, in my attempt to equip myself to make my own bullets, and having a .357 Magnum (or 2), a .45 Colt Redhawk, and a S&W 629 5" .44 Magnum, I believe I need to order gas checks in 35, 44, and 45 calibers. I have picked Hornady, because none of my molds provide crimp grooves for gas checks, and theirs are designed to crimp into the body of the bullet during sizing.
If use of gas checks is marginal or the subject of some difference of opinion, let's say I would want to use them and skip the debate. If the gas checks SHOULD NOT be used on some technical grounds, or there is some case why they are a waste, I would be interested in comments. Make of it what you will, but I'm just being clear about what I hope to gain as the OP.
