RE: 7mm grand slam loads
Thes seemed to be accurate. I say seemed because we set the target up at 75 yards instead of 100 to get my wife used to her 243. I was making the holes touch with these 145's, but that was at 73 grains of magpro. At 75 grains, they went all over the place. So, any guesses on what my FPS is on this load? I got to save up for a chrony. EJ
