These look to be Speer Gold Dots. I’ve shot them with faster powders, H322, N133, etc
Never tried TAC with the 62 Gold Dot, but I have shot the 62 Hornady BTHP with 25.1 grains of TAC. My notes show sub MOA groups out of my 1:7 twist bolt action.
FWIW, I settled on 24.5 gr of TAC with the Hornady 62 gr BTHP as our primary load in our AR-15’s. Has been accurate in twist rate of 7”, 8”, and 9” AR’s. Might be a good starting point for you to see what your rifle prefers. Let us know how it works out.
I just ordered 500 of the 62 gr bonded bullets and will try a few loads in my AR’s with TAC, X-Terminator and maybe another powder or two. Post up results when I am able to do so.
