Thread: Kimber Montana Ascent 280AI Load Development

59gn did much the same as 58.8gn. Interesting the 40 thou shorter COAL has (I think although small sample size) reduced pressure as speed has dropped from 2850fps. No pressure and I feel there is another node above 59gn but going to now settle at 58.4gn and 0.5 MOA a little over 2800 fps.

Anyone able to confirm the BC of the 180 eldm? Seen two Hornady sources quote .777 and .796.
