I recently bought a Remington 700 Medium-Long Range Police Rifle chambered in .338 Lapua. 1-10 twist barrel. Now, about me a little....I shot on the Michigan Army National Guard Rifle Team for 9 years, I have gone through Sniper School, and shoot in long range competition. BUT, this Lapua is driving me crazy. I am trying to figure out the "best recipe" for loads that this gun likes. I just can not get the gun to group GREAT groups. With my .308 I can shoot 10 shots that you can cover with a dime at 200 yards. This Lapua, shooting a 3-shot group, I can get 2 shots to, touch, but almost always get a flier about 1-2 inches out. I am using Retumbo for powder, 94 grains. I am using Lapua Scenar 250 grain bullets, and have tried Sierra Match King 250 grain bullets. Also Berger OTM 250 grain. I get the same results with all those bullets. The gun was purchased brand new, and there is only about 300 rounds fired through it. I am also getting horizontal groups.......5 shots in a horizontal line measuring about 1.5- 2 inches long. I have a Night Force Bench Rest 16-42 Power Scope with a Night Force 20 MOA steel base and steel rings. All lock tighted down. I just can not figure out why I can not get a 3-shot one hole group.....like I can with every one of my other sniper rifles. Any suggestions as to here to look?
