RL 23 will do the same thing. Ask me how I know LOL
Not goodAll I have is some suggested loads from a gunsmith and I ruined a bunch of expensive brass for a 280 AI messing with it. I have almost a full bottle of it and would give it away to someone local if they want it Im snake bit on it. I started at 57.0 grains. 58.6 was blowing primers out in my 280 AI with 162 ELDX bullets
My 7mag likes H 4831, my gun didnt like it but a lot of people say theirs does. I'm a retumbo fan. I want to try H1000 eventually.What is another extreme powder option for 7mm Rem Mag? Components I’m using is 168 Berger hunter, Nosler Brass, and CCI 250 primers. I’m not a fan of Reloader 22 due to pressure spike in hot temperatures.
