I am going to load some up for a buddy of mine's Rem model 7. It has a 20" barrel on it. This gun is strictly for hunting out to 400 yards and mostly in the woods. He gave me some 140 B-tips and IMR 4350 powder to load for him. His uncle(who undoubedtly just took a shot in the dark) loaded some with this combo in 47 grains and it shot like crap 6" at 200. I am thinking the powder is too slow for the short barrel and thought about loading it with Varget or Rl-15. What do yall think?
