[QUOTE="climb-101, post: 1066711, member: 31921"] i did some more testing today and shot over the chronograph to see some speeds. I did 3 shots of each 80, 80.5, 81, 81.5 I am still getting a slight ejector mark and a few still get the mark/wiped areas but not all. The chrono was a chroney beta master, 7' infront of gun, 70 deg outside and sunny. here are the speeds [U][B] 80 grains[/B][/U] 2581 2585 11ft/sec deviation and 2578 average 2574 [U][B]80.5 grains[/B][/U] 2588 2589 18ft/sec deviation and 2594 average 2606 [U][B]81 grains[/B][/U] 2614 2600 23ft/sec deviation and 2601 average 2591 [B][U]81.5 grains[/U][/B] 2608 2621 26ft/sec deviation and 2621 average 2634 according to the sierra manual to be around 2600 is should be around 86.5 grains of h1000. now that i have an idea as to what the speeds are, would i be ahead to drop down and try 79 grains h1000 in hopes to reduce the pressure even more and get rid of the slight ejector mark. 80 grains had the smallest difference in speed and was plenty fast coming out the barrel as well as having the best group on paper [/QUOTE]
