i use 42.3 gr in LC brass to push a 168gr pill with federal 210 primer. I get same results from this as 41.3 gr of imr4895 in the same cartridge.

I had some good success. 41.5, 41.8 and 42.5 all were touching. They had the least amount of spread. Ill have to load up some more and seek who wins. No signs of excessive pressure, no cracked cases, no blown primers.
