Re: Loaded rounds laying in sun
I've shot the temp. stabilized h4895 from below freezing to a hot summer day( in my 25wssm), and the change is 100 fps or so, or exactly what you would expect with any other powder. The rifle, cartridge case, and primer aren't temp. stabilized, why would you expect the same speeds if any of those are subject to temp. extremes. I've seen similar with other h powders, but this one stuck in my head. I go for what shoots well in both high and low temp ranges and don't try to trick the system. I am lucky here in N.D., I can wait a few days and get both extremes.
