6.5 Grendel Build

[LRRPF52]

Any chance you could share the load for the 120 BT. I have a new 12.5 inch upper that will be my suppressed deer hunter. I have about 150 of those and thought they might do well in the Sbr. The 129 ablr is just unobtainable right now. I have some of the 95 grain trex with tac loaded for a test run. Only have 50 of them and they are out of stock again. I am out of xbr. Options available are cfe, tac, or h322.

There are 25 different loads in the 6.5 Grendel Handbooks for the 120gr Nosler Ballistic Tip, 6 from Alexander Arms, 4 from Western Powders, and the rest from various forum members.

For TAC, start at 27.5gr and work up to 28.8gr.
For CFE223, start at 29.5gr and work up to 31.2gr. This one will run your gas system pretty hard if you don’t choke the gas and spring it stiffly.
For H322, Nosler has some very conservative data, which is lumped in with the 120gr E-Tip monolith, so I’m not sure what the actual top end is for H322 under the 120gr Ballistic Tip.

Of all those powders, I think you might like TAC the best.

How do you have your 12.5” configured?
Gas port diameter?
Recoil spring length?
Buffer type/weight?
Carrier?
Gas block?
