I was shooting my neighbors rifle last week, custom 700 with a 24" barrel, 8T, #5 contour, Gentry muzzle break.
We were trying some new bullets and powder.
first, 127g Barnes long range-case full of R#26 = 3150 with small groups
130g Accubond, case full of R#26 = 3150
Lapua brass in all loads
Fed 215's in all loads
No pressure signs, was necking all the time
We did not try and Nosler 125g partitions.
Good day all the way around.
