.43 Mauser with Hawk .446 350gr SPFN

[dark_timber]

I have managed to secure a few boxes of Hawk .446 350gr SPFN for my M71. I have not been able to find any smokeless powder loads for bullets that are not lead. Has anyone one ever given Hawks a try in their mighty .43?

I was thinking of starting with the published data for 350gr lead and working from there. Any thoughts?

I ordered mine through Summach Sports and they were great to deal with. Here are the .446 bullet offerings from Hawk:

Use Hodgdon 45-70 "Trapdoor" loads.

I also use hodgdon 45-70 trapdoor load data in my 43 mausers for all weight bullets. I dont use jacketed but im sure there is data for the jacketed 350's on hodgdons

Thanks to Andy and Evanguy for the suggestions. I'll have a look and let you know how the Hawks perform.

Might pick-up some 340gr lead bullets from Bullet Barn and try them as well.
