Best 6mm-284 loads long range hunting 105gr or 115gr?
I'm struggling a little bit with a new gun. I have perviously shot Retumbo and 115 VLD's in my older gun and they worked great. The new gun has a huge deviation in fps (70-100) so I swamped the primers from CCI 200 to CCI BR primers, a little better but still bad. At 300 yards it's shoots about 2-3" groups at best but at 100 yards it's 1.75-2.5" (horrible). Is it not stabilizing the bullet at a 100? I have Brux 1 in 8 twist in a 27.5" barrel; shooting 52.7 gr Retumbo. Also why the huge spread in velocity? I'm thinking about trying 105gr VLD's with a few powders (Retumbo, H4831, & H1000) any suggestions? I would like to take this gun to Montana in Oct. for deer and antelope but not if it's shooting like this.....
