I have a loaded springfield 1911 and I would like to reload with imr4227 powder but I can't find any data for it can anyone help me find this info.
Thank You in advance HITTMAN420

4227 is not appropriate for .45 ACP, that is why you aren't finding data for it. It is much too slow.

Yup, to slow. You might want to get a couple of manuals or look up some of the online manuals from the powder makers like Hodgden for appropriate powders for the 45 ACP.
