I'm just a little curious about what the maximum accurate range for my rifle/cartridge will be once I get it back. The rifle is... should say was a remington sendero. It is currently undergoing a substantial accurizing process including new match barrel, bolt sleeving, glass bedding, full action blueprint, and firing pin bushing/trueing. Should be one hell of a tack driver when I get it back. Its going to sport a Sightron SIII SS 6-24x50 Mildot, 20 MOA base and TPS tactical rings. Will be chambered for .300 win mag. My handloading is pretty good, I know a should get a few extra things after reading some posts on this board. I can do my part from the shooting end of things. My question is with this setup shooting 200 grain sierra matchkings at probably 2800-2900 fps what kind of maximum range should I be looking at driving out to before the accuracy falls apart? How much difference will neck turning the cartridges make? P.S. For gun techies does anyone have any experience with bolt sleeving and the firing pin work I described, my gunsmiths say it is the greatest thing since sliced bread. Any comments?
