I'm new at reloading. I have a Rem. Varmint 22-250 Bull Barrel, 1-14 twist and looking for the best combo for up to 400yds. With cheap factory loads from wal-mart of Winchester 45gr. I hold 2.3†groups at 200yds. I’ve seen a lot of great input on this site and hoping to get some good advice from everyone. I wished I would have looked on this site before buying my gun, I would have got one with a tighter twist to shoot heavier bullets.
