[QUOTE="trophyhunter170, post: 695048, member: 30392"] I can believe the 7MM Rem Mag velocity, but in considering the case capacity of the 7LRM which I believe is around 100 G of water, I may be wrong but my thoughts are that you are loading below minimum charge to get that kind of velocity. If that is the case, I would be careful. A low charge can be affected by a number of things especially cold weather and they can create pressure that can be very destructive. I would call Aaron at Gunwerks to make sure that your loads are above the minimum. That is amazing velocity for that powder charge in that case. My 7MM Dakota Imp. Case holds 97 G of water which is real close to your case and it takes 78.5 of H1000 I get 3,145 out of a 26 inch tube with a 8.5 twist. My finale load I selected was 81.5 of Retumbo @ 3,175 with a 177 Caurterucio. This load consistently averages around .280 with an ES of 0 to 20. I considered the Ruger case but decided on the Dakota because I felt it would be easier to form the brass due to neck step down. My case design did exactly what I wanted and this is the most accurate rifle I have ever owned with the exception of some bench rest rifles. It also has a Stiller 300 action with a jewell trigger. My barrel is a Krieger Fluted with a Remington LV Taper. I have a G7 Night Force 5.5 to 22 x 56 scope on it and it is stocked with a McMillian Game Scout stock. Gun and scope weight is 11.5 pounds.
