After hanging around this site for a few months, I decided I wanted to try my hand at some long distance shooting. I have hunted all my life and have several non tactical rifles in various calibers. I don't consider myself a crack shot, but I don't feel I am lousy either. Anyway, I decided to start fairly cheap and purchased a Remington SPS Varmint in .308. I replaced the stock right away with a McMillan A-5 from Third Generation Shooting Supply. Tonight was my first chance to shoot the rifle and I only took along cheap Remington and Winchester 150 grain lead nose bullets to break-in the barrel. I don't know what I was expecting with these bullets, but I couldn't get them to group any tighter than about 1.5"-2". I realize this could be shooter error but has anyone had similar results? I am waiting on the rest of my handload supplies to get in so I can try some 175 grain MatchKings. Should I expect the groups to tighten up that much or should I look into other issues? Thanks in advance for the help.
