interesting data. i didn't realize H4895 had half of the temp coefficient of BenchMark. where did you find that info? did any other powder that is in the usable range of the 6.5G have a lower temp co?
thanks,

Think I stole it from Klem!
Just got a keg of A2460, based off this chart. In the Western Powders Manual, its almost identical to TAC in speed and supposedly 1/3 as temperature sensitive.
Varget is the most stable listed in the Grendel range but kind of slow. Only got 2263 FPS with 26.8 grns (Speer Manual max) and 120 Gold Dots. The manual claims 2420 FPS with a different case/primer, same length barrel. IDK?
