I guess my FA 454 had a fast barrel (7.5"), becasue I shot the 300 XTP @ 1775 fps all day long.
Wouldn’t surprise me either way. I am just going by what my Hornady book has listed for a 454 using a 7.5 Freedom Arms with a 300gr XTP. The max velocity they have listed is 1650. (I wouldn't use that powder which is why I listed 1600 above.) But again, that is only one manual with one test gun. LOL
