that's a good, mild mid range load that'll kill deer a long ways out. I shot that load ( a couple of grains more powder) for years until I went to rl25.Well I settled on a load and after doing some adjustments I think I got a good load with 140 gr Sierra Pro hunters Seated at 3.690 with 75 gr of IMR 7828 Heres 5 off the sand bags and 3 off hand 100
