[QUOTE="Critter Picker, post: 2194136, member: 111781"] Very interesting article, I've been casting for almost half a century and still picked up some unknown info in this article. The OP never stated if he was using gas checks, but after many years of shooting cast bullets I'm still on the fence with them. For the most part I can usually achieve the same degree of accuracy without them, but I can drive a bullet faster with the gas check and still maintain the accuracy without leading. However adding a gas check makes one at the mercy of a purchased item that can, at times like this be tough to acquire. I have an old NEI mould that casts a 30 cal. 165 grain GC bullet that I have driven to 2800 FPS in 3 different .308 rifles and to 2600 inn 2 .308 handguns without any trace of leading. Peak accuracy was achieved at a little less velocity , but point is that jacketed bullet velocities can be achieved with cast bullets. RCBS has a 405 and a 350 grain gas check mould in 45 caliber that I have used in a few 45 caliber rifles with excellent results. The 405 hits with authority on both ends , and I wouldn't recommend long bench sessions with it. I have taken both deer and bear with it and it does a fine job. I did have a 500 grain version of the same bullet, but just couldn't take the punishment of developing a load for it. If you have a heavy enough rifle it could be a good option also. [/QUOTE]
