[QUOTE="Huntnful, post: 3044754, member: 116563"] My baseline case was a 180 ELDM at 3.590 COAL to the lands. After the first 50 rounds, it had not changed at all actually. I expected it to, so I checked it again haha. I’m personally looking at primers, ejector marks, bolt lift and velocity. With more time behind it, and more firings on the brass, i’ll get a better and better idea of it I think. As well as maybe more people shooting the cartridge. I think getting unreal velocities, normally correlates to getting unreal pressure hahaha. But there isn’t much info on this one out there to compare velocities to. So I will try to be realistic when I share them. And not just share a max load velocities with little bolt click for bragging purposes. I want realistic velocities, well under pressure with whatever powder. [/QUOTE]
