Short barreled 6.5 saum/prc

[lancetkenyon]

20" 1:7.5" 6.5SS w. TBAC Ultra 7.

I run a few hunting loads in mine.
156 @ 3001fps run hot w. N565, .3gr off max load. Brass won't last long at these speeds, 3 firings tops.
144 LR Hyb @ 3065fps w. N565, 1gr off max at just under 3100fps. Brass has been fine with 3 firings so far.
129 AH @ 3161fps w. H4350, 2gr off max. Hit 3250 before pressure. Only 2 firings on brass so far.

My weekend steel load (to save brass life) is a 144 LR Hyb @ 2959fps or 156 EOL @ 2899fps.

I built my Dad an 18" 6.5 PRC on a defiance action with a Carbon six barrel. Only did a little bit of testing so far but I was able to get the 123gr AH to 3107 using StaBall 6.5 before I started getting faint ejector marks on the brass.

Chopped my 6.5 SAUM from 24" down to 20". Getting 2,990 fps with H1000 and the 139 scenar, suppressed with Ultra 7. I'm not leaning on it either, longer brass life outweighs pushing it an extra 50-100 fps in my mind.

This thread should be called "how to turn your 6.5prc down to 6.5 creedmoor speeds".

Don't take it personal fellas, I couldn't resist. I also hate having 32" of combined barrel length, but man I don't want to give up the velocity.

I took my saum to 16" and am getting a safe and accurate 2960 with 142s
Little better than creed velocities..

That's actually really good. I could live with that.

Yeah I'm really glad I didn't go PRC, the saum is a better case

20" saum w 140 EH and N565 is 3032 for velocity. 20" 6.5 PRC w 130 JLK at 3110 w N565.
