I've been looking at hard cast bullets for my heavy +P 45 Colt loads and noticed that some of the bullets have gas-checks and some don't. What are the advantages of gas-checks, and should I be looking for bullets with or without them for my heavy loads?
Only place you need GC is maybe in a 44mag marlin rifle or a 45-70, 444, or 450. And only if your going to push them to 1900-2200fps.
Most pistol calibers its a waste IMO if your velocity is under 1500fps. I need them in my 460smith. I get serious leading past 1800fps and 325gr bullet. I know if its me, I wouldn't bother for a 45colt even +P loads.
