Ah-Ha! 44 grs of IMR 4320 and 140gr TTSX
An Amigo called last night to see if I wanted to join him at the range today. He wanted to do some load work up with his latest 35 Whelen and I asked him about his loads. He said IMR 4320 was showing some promise - the light came on. Why not try the powder in the 7x57.
It was classic how the 3 shot groups tightened up as the powder grains increased. 11/16" groups, but I think I can get better if my fingers are not half froze. It warmed up to 15 degrees today.
Chrony average was 2820fps.
