Re: cooper 260 rem
the rifle was used to shoot a 6x6 bull elk dead center in the side of the neck, passed through completly. 130 grain partition. light load.
my main sugestion is to get the desired twist rate for the longer bullets that are required at long ranges. I am a beginner and was shooting 1moa at 300 ( 3 inch group )yards with little work.
bergers shot well but not shure about using them as a premier humting load, i am shure they would be fime with correct bullet placement.
I have not got a chance to shoot any light bullets yet , I expect my group size to shrink in half, as my rifle has a 1-9 twist, most of what I read says you need 1-8 twist to stabalize the longer bullets that people are using. but I believe real bennifit is out past 500 yards
