I have a box-stock Ruger M 77 .308 with a good scope on it. I've always been more of a pistol shooter and reloader but got out
the rifle this fall to shoot some paper. I can get a .75 inch group at 100 meters on a good day. What should I expect at 300 meters? A 3 inch group was the best I got but its not consistent with that. At 100 meters it seemed to shoot better with 38.5 grains of IMR 4895 and I've tried a bunch of different powders and loads. I'm using a 178 grain Hornady BTHP. Its my understanding that getting the bullet as close to the lands as possible is best as long as you've got at least .125 inch of bullet contacting the brass. This gun has a long chamber so that's how I've been seating them. The question for me is just what is the best I can expect at 300 meters? I can knock down 10 silhouettes as fast as I can load, sight and shoot but I'd like to be able to try some targets as well. Should I try less bullet or more velocity or am I at the limit with this particlar gun?
Any advice would be greatly appreciated.
