I shot my rifle today with some mxed feelings about it. I broke it in with 20 shots,, cleaning after everyone for the first 10.. then 2 five shot groups after.. shot decent for factory loads.. I went out to the range today to shoot some more factory loads after the recent muzzlebreak that was installed. first shot shoots pretty good. but everything after sometimes is way way way off. any ideas? I am shooting some 180 grain remingtons.. the ultra bonded ones.. terrible goups. one shoots on taget.. next shoots 7 inches high.. another shoots low lol. any chance my rife doesnt like these bullets? seems weird. barrel is a 26 inch shilen barrel.
As to your first question about load data with the 208Amax, Retumbo and H1000 are the 'go-to' powders for the 300RUM. Start around 89grains and work up.
As to the troubles you are having with your shifting point of impact, check every mounting screw on the rifle - action bolt, tang screw, scope bases, scope rings. By check, I mean with a torque screwdriver so that you can be confident that everything is screwed down with the appropriate amount of pressure.
If that does not solve the issue, the next thing to look at is your scope. Might have to send it back to the manufacturer to see if there is an internal problem there.
