I did not get any signs of over pressure in my AR10 with 43.1gr of RL15 and 175gr SMK. Actually I was kinda dissapointed in the velocity, got me to about 2530 average.

I was reading M118LR (uses the same 175gr SMK and RL15) by the military gets a smoking 2700 fps! I am trying to get about 2560, at that velocity it will keep me supersonic past just over a 1000 yards, which is I why I went 175gr SMK's in the first place, to have a 1000 yard round.
