I live and hunt in the Austin Texas area. Read Its freaking hot when I hunt. Factory loads are showing signs of preasure at 80 deg plus so there are days I can't hunt nor shoot. I need a powder that will be relativly stable up to 90 degrees or so. The gun is a Remington Sendero 300 RUM that loves the 180 Swift Sciroccos(sp) from the factory but it seems a little on the hot side. any ideas?
