Thread: 300 Blackout Suppressor - fixed the bastard...

Hey mate, I've ended up with 10 grains of AR2207 behind the SMK. It pushes them at just over 1000 fps but with the Sierras costing $1.29 per pill, I won't be cutting loose with it...

I have had problems with my gun cycling subsonic loads. I have been using Accurate 1680. I understand that H4198 is the same as AR2207. I think I'll give your recipe a try with H4198. Glad to see you are still out there blowing holes in paper. Josh and I were stretching our skills a bit shooting a 14" steel plate at 975 Yards in really tricky wind conditions. We learned that it only takes a 2 mph wind change to take you off that small a target. We had some success but got more education than satisfaction.
