So I've been lurking around this forum for the better part of a month or so regarding velocities and I’m at a lost. I’m running a Ruger American Predator (22” barrel) with a can that I dropped into a MDT XRS chassis and have been working on load development centered around Hornady’s 140 ELD-M’s. Using H4350, hornady brass and CCI #200, I started out at 41.5gr and worked my way up, however my velocities seem very low compared to others with that length barrel. At 41.5gr I was hovering around 2,425 and have since worked my way up to 43gr moving at an average of 2,530 with no pressure signs, but seemingly very low velocities. Thinking it could be my chronograph or barrel, I fired some factory Hornady 140 ELD-M rounds and averaged 2,640.
The only thing I am very happy with is my accuracy with my loads, seated .020 off the lands at 2.223 and COAL 2.846. Picture below is 43gr of H4350 averaging 2,530 at 100 yards. Anyone have any suggestions on where to go from here?
