Is that IMR 4227 or H4227? I tried the only load listed in Hodgdon#27 before the rain shut me down. The load listed was 17.7grs IMR 4227 with a 250gr “REM LEAD” whatever that is.
It only gave around 1025 fps , with horrible accuracy, and unburt powder in the action/barrel. I loaded up 5 more at 18.0, 18.5, and 19.0 grains just so I could find out where the accuracy is and when it’ll start to get a cleaner burn.

I’ve been shooting a 275gn bullet with 23gn 4227.
