Edit to add, this is assuming heavy bullets in the 220-245 grain range. Things may be different if you’re loading lightweight subs

There's actually a good bit of load data for 4227 subs, even on the Hodgdon website


Get the F out of the BATFE. The F is guaranteed by the US Constitution. Those other letters are not.
