300 SAUM Imp

Wow.This right here is WHY I gave up on shooting for serious accuracy!!! The last picture with ALL those cases seperated by weight/ capacity is where I was one day and I realized ” what the hell am I doing?” This is supposed to be fun AND a hobby. I then looked up HOBBY in the dictionary.It states, “Activity done in ones leisure time for pleasure” That’s the day that I made a change.
I really appreciate the success that you have achieved. It’s not easy and is definitely EARNED.
ALL THOSE ALLIGNED CASES JUST MADE ME SNAP!
 
The 30-6.5 PRC has had me interested since the PRC started getting brass from Lapua, Peterson, and ADG. Seems like it could be a great cartridge. I’m interested to see your results with it!

So what I am seeing is that the weight difference in the cases is not proportional to volume.

Never seen a case where it was proportional yet. Evidence it may "correlate", but I'm a ways out from being sure of that. Some brass does, like lapua 6br, but still has outliers within that. And some brass doesn't really at all.

My plan is to form 50 CT box 1 from heaviest end, and form 50 CT box 10 from lightest. When I go through those we'll have the answers.

Alex,Tom. What was the thought process to go to the 30-65prc? Brass availability?? And are you hoping to improve it or run it stright?? Thanks. Kevin Lepine

I'm not improving it at first, but there's a couple reasons. Lapua and ADG both make brass. The thought was similar to what we see with the BRA....you can run 103s 3050 with either 33 grains of powder or 31 grains, guess which is agging better. This may or may not be too small? I don't know yet, but the brass I formed in my first box rivals lapua 6br for volume consistency. The thought was also about a potential use for light gun...but forming brass at 2850 with 197s is pretty much kicking my ass lol....so we'll have to see about that.

Here's box 1, heaviest end of the lot. I lost case 50 screwing around, so tossed a wsm case in there for comparison.
