I am running a little low on powders and thinking about trying something new. I generally shoot 50-55gr V max, Nosler Varmegeddon BT, HP, SP. I am looking for accuracy but also good velocity to shoot a little flatter. I have tried H335 but only with 55gr v max and wasn't impressed, H322 and Benchmark seem to do well and I have IMR4198 on hand for 45-70govt if that will work. This is for a bolt gun used to shoot varmints and targets from 100-300yards. I plan on using 50gr v max exclusively for paper punching and 53-55gr Nosler Varmegeddon BT/HP and V max for varmints.
Also, I made a spread sheet with each powders velocity and CUP/PSI data and it got me wondering if I chose a powder with a lower PSI/CUP rating if it would give my barrel a little more life. Based on what I've compiled there is no rhyme or reason some powders have a higher velocity but a low CUP/PSI and some with lower FPS have a higher CUP/PSI.
