AR-10(TU) .300 Remington short Ultra-Mag. ...the (TU) is <span style="font-style: italic">very</span> accurate for a semi.

The Ultra Mag bucked around quite a bit with the 180 & especially the 190 grainers at 2910 fps.
It was difficult to shoot using a bipod since it was some work to get it back on target. I put a muzzle brake on it and it tamed it consideraby. I prefer to shoot off a bag, but now I can shoot off of either.

Hell yes that's awesome shooting and I know what you mean about it "bucking" around a bit. PRI adjustable gas block and a suppressor brought recoil back down into what I feel is "semi 308" status
I got mine put together (built a new lower for the <span style="font-weight: bold">used</span> upper) last year and run it suppressed with a PRI adjustable block and she put this group together with 210 VLDs at 1150yds. My best at distance (with it and them) so far.
I had equally good results with the 185 and 190 VLDs but didn't progress beyond 100yd load development since the 210's shot as well at distance.
One thing about it, the Armalite's 300 SAUM is a shooter.
The 300 Ultra SASS
