It is interesting to come back over here and find this thread I started so long ago still alive.
I joined AR15.com and got into 80% receivers and milling and so on. Last December I was invited by Green Mountain Rifle Barrels to test a variety of barrel twists (1:6, 1:5 and so on) with nothing particularly applicable to cast bullets. That changed when they sent a 1: 14 barrel. They are 18" barrels with a rifle length gas action. I will re-running the cast bullet tests in the new barrel to see what they do. I have some bater bullets as well as the RCBS bullets and will see how they do. I will post results here as well as over there. I also donated funds to help keep this site going.
