[QUOTE="Bowfishn, post: 1350379, member: 56875"] Your lot of powder is close to my lot for BA QL shows for my lot that is adjusted for velocity obtained with Magnetospeed 49 gr RL26 with Hornady Brass 53.5 gr H2O and 147 ELD-M bullets seated 2.800" @ 3001 fps but at a pressure of 73573 psi. 50 gr shows 3060 fps but at 80026 psi. That is if you have a 24" barrel like what came with the rifle. If it was 26" you could do it with 67177 psi, if it was a 28" it would be 63145 psi. This is all based on pressure needed with RL26 to get a velocity just over 3000 fps with 147 ELD-M bullets, and assuming your Chrono or what ever you are using to measure speed is correct. ( I may suspect your Chrono is not giving an accurate reading as over 80k should have shown problems, QL default ba for 50gr RL26 shows 2995 fps at 70373 psi pressure, which most likely would not have shown any pressure signs.) Reminds me of the load I was testing with 143 ELD-X that I got about 3050 fps, no sign of over pressure, but QL showed over 70k pressure. That was out of a 26" tube. I have over 800 rounds down my barrel with RL26 and 6 different bullets tested, and have come to trust QL for accurately predicting what I will get from the loads tested. Also Berger has a load listed with RL26 and a 135 gr bullet out of a 24" tube. Their load is showing almost exact speed with QL and QL shows 58030 psi for theirs. It is what you might expect from a company that wants to be safe on loads that will be tried in a lot of varying circumstances. Just be careful, you may be on the edge of problems. By the way nice group. [/QUOTE]
