445 SM powder
« on: March 01, 2014, 12:33:35 AM »
With this winter hanging on all I can do is dream about reaming my 44. The only good thing is I have time to read old post on reloading for it. Like  others some powder are hard to come by here. Cant find AA 1680  had a bad experience with H 110 /W296 Has anyone used A 5744 I was wondering about IMR 4198 have not found any load data for it thou . What do you guys use
DON’T get in a gun fight with a buffalo hunter there is no such thing as cover against a 45 70

Reamer is available!  ;) I only have 1680 data, I used H110 in mine with the 265gr FTX, so I'm not much help for ya.  :-\

EDIT: Hornady lists 5744 for all their .430" jacketed bullets in the 8th edition.

Hey guys didn't I read that the
357 max in the FAQs is usable on the sb1 or old cast irons  H&Rs
( kind of a controversial issue)
But the 445 supermag is not to be used on anything but an SB2

Maxi is fine on SB1, 445 isn't recommended on an SB1 due to the larger case head(.379" v .457") and fairly high pressure data in comparison, there's no SAAMI spec for the 445 and old data runs 43-47kcup compared to 36kpsi for the 44 mag.

 I know that 1680 gives top velocities and good accuracy but seems to have a lot of muzzle flash.
Out of a 20” barreled rifle I can see the flash even during bright daylight.
