I run them out of a 16". Performance has been pretty good, but not a fur saver bullet IMO. Shot coyotes from 50 to 525 yards with them. Hand loads have been sub MOA with a little effort. In my gun I have to seat them deep to get best accuracy, or jam them so hard that the bullets stick in the chamber when you go to eject a live round.(not a pleasant experience) They have always seemed to make coyotes dead pretty good, but have had some significant holes in them, too.
