[QUOTE="Petey308, post: 2771275, member: 106845"] the difference in velocity can easily be fixed by calibrating the Ba in QuickLoad. The things QL doesn’t allow you to account for, such as chamber dimensions, case shoulder bump, neck tension, primers, primer seating depth, twist rate, different lots of powder, etc, etc, can be accounted for by adjusting the burn rate (Ba) for the particular powder. Differences in all those things mentioned effectively change the burn rate of the powder due to how it directly affects it. You also change this figure when using QL for actual load development methods such as OBT. I think you’d find that if you adjusted the Ba to match your actual MV, you’d still find it was at an excessive amount of pressure. I’d do this for you and post it, but I’m not at my computer at the moment. There’s also the possibility that the round that caused the issue had some other differences you’re unaware of that compounded the issue and why it appeared so much different than the ones before it.
