The ballistics of the 16” AR15 bbl will be similar to a 15” bolt gun due to the gas system. Also, there will be a lot of muzzle blast with the standard birdcage flash hider. The blast can be focused forward with:

There are multiple loads for both the Nosler 30 cal. 125's in MidwayUSA's comments on each. I set my OAL to ensure .308" of the bullet shank was in the neck of the case. Others may or may not have been that short so start lower on the powder amounts.

I've loaded for a similar DPMS. The 2 MV handicaps of it being a gas gun and the short barrel can be overcome with shooting a lighter hunting bullet. The 125g Nosler BT does well.

Here is a QuickLoad forecast for the powders you have. Note the shorter than SAMMI for the overall length. This is to have .308" of the bullet shank in the neck of the case. These should be mild loads at ~50K psi.

Bullet : .308, 125...
You are not going to find many books listing data for an OAL of 3.5" or more. Modeling non-SAMMI specs' is 1 of the major advantages of QL. BTW, RL-33 is on some store shelves.
Good luck.

Yea, that’s the way to do it guys, using a cup and core paper punching bullet for hunting big game. Old man J.A. Nosler should be rolling in his grave. :shock:
Love to see a near twin BTLR to the 6.5mm 129g ABLR. Maybe plus some on weight & BC. Cheaper to shot than the AB, use for smaller game/large varmints, hopefully great on paper at range, more uniform meplat than the CC.
If you are using an AR, you can expect 50-100 fps less than forecasted due to the gas system. Also, a shorter barrel than modeled would make a big difference. Good luck!
