Just getting back from the hunt with my Dad. Ended up loading 62.5gr of H4350 with the 131HH as my Dad liked the recoil with that load. Chrono-ed the load at 3155fps and it was the first time my dad was able to consistently ring the 300yd steel with his Ruger!
We ended up with a 3/4 of mile stock on some antelope and he a great shot from a pseudo prone position at 244yards with a sustained 20mph crosswind. The antelope stood there for a few seconds and collapsed!
I want to thank everyone for their input.
