Can anyone reccomend bullets that I can shoot in a Ruger M77 .338 Win Mag for 300-500 yd shooting. All shots will be on paper. My rifle will shoot one-hole groups with aa 2700 and 200 gr Speer spitzers, and shoots IMR 4831 very well too. I just got the rifle, but it shoots 200 gr CT Ballistic tips and 200 gr Winchester Factory Power-Points in one hole groups as well. Is there any reason to play with the 250-300 gr bullets for shooting at 500 yds? BTW I only have a 3x9 scope. I am limited by this sight picture, but that is part of the challenge I want with this particular rifle.
