[QUOTE="Clay Target Guy, post: 1639980, member: 68920"] OK went and shot this yesterday, I loaded up some R15, H414, and Super-performance. Due to time and shooting some other guns I only had time to shoot the R15. I loaded up 32.9 gr, 33.2, and 33.5 gr to try. All gave really good ES and SD's and vel. was not bad either. the 32.9 gr load was 3189 average, with an ES of 25 and a SD of 13, the groups size was right at 13/16". The next load of 33.2, turned in a 3220 (best I can remember, I forgot my notes) with a ES of 15 and SD of 8 group size shrank to .6 (once again best I can remember without my notes). Last up was the 33.5 load, which turned in a 3258 average vel. with an ES of 9 and a SD of 4! groups size shrank again to a .5" group. I could not see any pressure signs but need to go back and look at the brass one more time. I do feel that the 33.5 may be getting close to max as the bolt did feel a little (very little) more stiff that the 33.2 load, but to be fair, I did forget to put the 33.5 load in the shade while the barrel cooled from shooting the other shots and it was 95 deg. here yesterday. When I went to shoot the 33.5 loads, the barrel was cool but the rounds were hot. Hope to get back to the range with the other loads and give them a try (since I already have them loaded up) but I think R15 is going to be a tuff act to follow. I feel I could tighten the groups a little by paying with bullet seating depths. [/QUOTE]
