7mm SAUM AR

Nice! I have all my stuff ordered. I'm going to start with some 162 ELDMs and accurate MagPro powder. We'll see how it goes!

After this deer season I want to try a few other powders like H1000 and MagPro. Really want to get out to a PRS match or two and put the rifle through its paces next year

That would be a hell of a PRS rig! lol

.243w, 2x fired starline brass (not annealed) h4350 and a 108, 36-41.5gr in .5gr increments = 2704-3035fps
same brass & loads but new = 2660-3012.
not a big difference there.

Minor load work update:
I picked up an expanding mandrel from Cortina and reworked my brass process.
Shoulder bump .0025” with full length die(no neck expander on the de-caper), & .282 neck mandrel in the mandrel die. All to brass with multiple fires. The test was 10rds, average velocity of 2873, SD of 10fps, .75” group at 100.

I did stretch it out with some fire forming loads, I’ve got to get back to reading the wind. Had good consistency out to 600 on a 10” gong.
