Quick question for those of you who use Quickload. I'm testing out a couple different 155g bullets (Scenar, Sierra Palma 2156) in .308 caliber, using the same powder (H4895). Did some preliminary testing with both bullets and got some chrono data, now am truing up the data in Quickload for purposes of additional load development. I've measured and input all the correct cartridge and bullet data factors available to me, then used the burn rate (Ba) to true up the velocities to match chrono data. However, I get different burn rates for each cartridge even though I used the same powder (same can) for both. Burn rates are .553 vs .5843, so a decent difference. Is this one of those things you just live with, and chalk it up to how each bullet performs in the gun? Or are there additional steps that I might consider to further fine tune my QL predictions?
