I’ve only got two 308s left, and M1A and a 16” barreled FAL, lve shot only 150gr SSTs using H4895, I’m just not sure either of those two rifles would like a lighter bullet. I do have a good load using 125 gr Power points in my 300WM, it is one flat shooting round! But that’s out of a long barreled bolt action.H4895 is my lighter .308 bullet powder of choice...but talk about unobtainable and expensive. I've only got about 2.5lbs left, and I doubt I'll be able to replace it. IMR-4895 is close, but you lose the temperature insensitivity. I've got MOA or better out of several 130 - 150gr hunting bullets out of my 18" Wilson Combat barrel with H4895.
TAC is my cheap alternative, but I have to do load development for the temps I'll be hunting in...way too easy to end up with pressure issues with it. I was using TAC with the 150gr Interlock on my thermal stuff.
Plenty of professional resources online so you don't need to copy a home recipe and end up in trouble.
