Looking for load data for my revolvers and carbine. I have a new can of IMR4227 and would like to use it but cant find any load data for it. I shoot 250gr cast for cowboy shooting so about 850 fps is what I am looking for. Is this doable and if so any suggestions
IMR 4227 in 45 Colt
- Thread starter lyktohunt
- Start date
Several years ago I loaded IMR 4227 for a Ruger Blackhawk using Hornady 250 grain XTP jacketed bullets.
The data came out of one of Hornady's manuals from the early 1990's.
The load I was building was never intended to be shot out of light framed single actions as it was pushing the performance level of a .44 Magnum.
Recoil was pretty stout as was muzzle flash.
If you have a heavy framed Blackhawk go ahead,but there's better powder choices for light loads using cast bullets.

Thanks ,just thought I would try the 4227 route as i have it and will not have much use for it. I will go back to the Unique or maybe try trail boss in the hope that it is cleaner

These are the only two loads that has been tested by members of that forum. You should be able to work down from those two loads to get where you want to be.
You might find other data by doing a search on this forum:

IMR data center prob has the data you are looking for but
I think cost wise 4227 is a bad choice 2+ X $$
it measures real good but is twice the weight per charge you could burn up that 1 lb with a single visit to the range on a fun filled day

IMR doesn't list the powder for 45Colt, probably for the reasons you state.IMR data center prob has the data you are looking for but

15.5 gr with a 250 gr bullet will get you around 830-850 fps. Not the most efficient powder for what you're trying to do though. - dan
