using nosler 130 gr ab, with imr 4451 , 91/2 rem primer, only shoots 2 inch group at 200yds. chrony 3125fps. was hoping a better group, no sign of high pressure.
I think you are on to something, i was expecting something around 3100 fps for that load, then i remembered the chrony was set to 9ft from barrel, my 22lr setup. I think a 264 win mag muzzle blast is creating a false reading. I will post follow up test results. thanks
I worked up a load straight from nosler loading manual, using nosler 120 gr. bt, p/n 26120, 58 gr imr 4350. rem 91/2 primer. 3504 fps. at 200 yds, three rounds into the same hole.
winchester model 70, .264 win mag extreme weather ss, 1-9 twist, 26 in barrel.
