Okay, thanks to all who advised from my last post. I took my chrono out, and shot several different loads with both the 150gr and the 168gr bullets. Conditions during the shoot were cool (approx. 64 degrees and 70% humidity) Results are as follows: All are with RE15 Powder 150gr actual shot - 42gr @ 2578 // published - 2500 @ 41.9gr actual shot - 44gr @ 2789 // published - 2600 @ 43.6gr actual shot - 46gr @ 2917 // published - 2700 @ 45.4gr 168gr actual shot - 40gr @ 2411 // published - 2400 @40.7gr actual shot - 41.5gr @ 2492 // published - 2456 @ 41.6gr (interpelated) actual shot - 43gr @ 2599 // published - 2555 @ 43.4gr (interpelated) actual shot - 43.5gr @ 2619 // published - 2555 @ 43.4gr (interpelated) In both cases my ending velocity is greater than the velocity published for the max powder charge.... 2800fps @ 47.2gr for the 150gr bullet and 2600 @ 44.3gr for the 168gr bullet. With the velocities being as great as they are compared to the published velocities, am I in approaching anything in the unsafe realm? Is the velocity directly proportional to the pressure? Or are they seperate issues? I individually checked each round after shooting and had no signs of high pressure.
