Re: 245 go lead in SBR AR load help

Always lots of variables. Without knowing exactly how the rifle is set up and exact load data, it's impossible to say. First thing on low velocity is the data is for a 16" barrel, so it will be slow. The problem is that if the load will cycle a 16" barrel it should cycle a 10". That'...

Re: 245 go lead in SBR AR load help

Re: 245 go lead in SBR AR load help

The only way a faster powder will help, is if the bullet is undersized and the higher pressure deforms the bullet helping it seal at the base. One of the problems with a lot of commercial cast bullets is they're too hard and small, and will not obdurate with a typical AR sub load. The Missouri bull...
