IMR 4227 and 350 Legend

[44Blam]

I seem to remember someone having luck with this combo but I could not find it with the search function... :(

I found Norma 200 to be good but a bit slow.

Not 4227, but I’ve found fantastic results with Alliant 300-MP under NOE’s 190gr 350L boolit. Just throwing that out there incase you have that powder on hand.

I'm just getting started loading for my AR. I bought a box of Matt's bullets 170gr, gc. Using Hodgdons on line data, I loaded 5 at 25grs, and 5 at 26grs. of IMR4227. I set my c.o.l. at 2.140". The 25gr load did best at 2" at 50yds. Both cycled well, and didn't deform the boolits or leave any leading at all.
