[QUOTE="montana_native, post: 282819, member: 12881"] [b]Re: 7mm Rem mag load advice[/b] Well, here is what happened today. After break-in per Shilen's recommendation, I shot some 150 gr Ballistic tips. Best group was 0.381" at 100 yds. Velocity was 3082. Then I got into the Berger 180 VLD's. 65.5 gr of Retumbo, 0.534" group. avg. 2701 fps. ES 39 66.5 gr of Retumbo, 0.430" group. avg. 2752 fps. ES 15 67.5 gr of Retumbo, screwed up the group when a guy next to me fired just before me so I jerked one. two through the same hole. avg. 2792 fps. ES 13 These velocities seem low? Barrel actually finished at 27". COAL was 3.385" and just into the lands which is cool because they still fit into my magazine. The brass and primers showed zero pressure signs. I just got done with a very thorough cleaning of the barrel and it was VERY copper fouled. The Sweets didn't work too well at the rane today. I may return tomorrow to try the 160 Accubonds and the 180 Bergers over H-1000. Thanks for any of your thoughts. [/QUOTE]
