You are roll crimping plastic cases I take it. You are better off using 3.5" cases as extra wads and neater crimp keeps peak pressures down. I'll test some lightfields later on and check out that powder. It appears from your uses better than Blue Dot, because when we got to 55gr with it and 600gr slug cases were sticking. You have done some great work. What brass cases will you go to? It is shame that Encore with long barrel cost so much.. and we keep telling NEF they are missing the boat, as they say, by not having 28" barrel. Ed
