Did like 45 of these yesterday and today. I had 45 brass and 50 125g FMJ but had to buy IMR 4227 which I haven't used in like 20 years or so. I did like it for something for 357 mag or the like. I just can't remember and it's not important anyway. I could work up a load for 10mm but not sure of a starting point and data is scarce. Something to think about anyway. I can use it for 300 blackout as the holster guy loves it if it shoots good!! Craig
IMR 4227 is too slow for 10mm and would need an heavy crimp to ignite well.
Thanks Wade. I can't even find data for 357 so I may have not used it for that. It must be a real slow powder as a starting point is 15.7g for 125g bullet. Oh well if it works and it should I can just use it for 300 blackout. Thanks again for your input. Craig
you would have been better off if you could have gotten some H-110.
I have used Little gun for years but couldn't find any. Thanks Craig
4227 would have been used for 44 Mag. Hodgdon lists loads for 4227 and 125gr.
