View Full Version : OOPS! I loaded IMR4227, NOT H4227!

I am working up a mid-range (~1500 fps) load with 260 gr. FPGC cast lead bullets in my Ruger SRH .454 Casull. I loaded 30.0 grains of IMR 4227 instead of Hodgdon 4227 :groner: . I am 10% under max as listed in the Lee manual. Do I need to pull 'em and start over?

I have reason to believe the IMR 4227 in the round containers is really old H4227 Extreme, despite Hodgdon's marketing claims. Regardless, the burn rate isn't that different when I compared "old" H4227 to "new" IMR 4227.

As long as you are in midrange level loads, no.
