OK, First off Specs: 7 RUM Sendero. All orginal except trigger and muzzel break. Powder= Retumbo Bullet= 160 accubonds Primer=215m rem=brass I have been loading for this thing and these are the best loads that I have gotten so far. If I keep load developing for this thing I am going to need a new barrel 93 gr has been the most consitant 93.5 94 gr getting a little hot with minor stiff bolt 94.5 stiff bolt lift and extrator mark It seems to be getting better but still not great. If you were going to pick a load which one would you choose. The one will the smallest extreme spread has alot of vertical. There was a 3-5mph left to right wind. All shooting was at 300 yards. Velocites are list along with group size. All loads were under MOA and I am not sure if my brother can shoot that good anyway Thanks for the feedback.
