445 Super Mag loading

cptmclark · December 6, 2007, 10:35 AM

I am reaming an accurate 44 mag rifle to 445 supermag to take advantage of the new IN deer hunting rule allowing pistol cartridge rifles (only slug before).
As far as I see, 44 bullets are built for handgun velocities, unlike several 45s.

Does anyone have experience or knowledge about jacketed bullets that will hold up at velocities from, say 1300 to 2500 fps?

Also, I don't see much guidance on 445 in rifle length barrels. Best info I find indicates AA 1680 may be best all around powder for this. I suspect that the longer barrel can take advantage of slower powder, but don't see any data for anything slower than 1689. HELP!?
