[QUOTE="just_jon, post: 1973928, member: 112153"] Those are the speeds I was looking for when I went with the STW. I shot a test with H1000 on Thursday from 77.7 to 82.2 grains (Berger max) in 1/2 grain increments. Top speed was 3,046. QL shows 82.2 grains as near max with a speed of 3,123. Also shot tests with H4831, IMR 4350, IMR 7977, and IMR 8133 up to book max and none exceeded 3,100. No doubt that I can push things a little harder since QL shows 82.2 grains of H1000 only reached 56,000 psi. Problem is there is not a lot of room left between book max and the "Dangerous Load - Do Not Use" loads in QL. In order to reach 3,450 with H1000, QL says I need 90.4 grains of H1000 (109% fill). I am convinced that I'm just wasting my time and components doing further testing with this barrel. [/QUOTE]
