In the summer I was getting 2998 with 80s through my 26" 1/6.5 which I am told is is a little slower than a 1/7.
I shot it 30 times in 40 degree weather and only threw 1 case away, probably because my velocity dropped down close to 100 fps.
Every group was 1 hole, so I probably need to back my charge down in the summer.
BTW, my dope was 2.5 mils at 500.
