45 LC hunting round smokless for Urberti 73 lever ?

[mr phil]

Started loading 45 lc for CAS. Now I want to load some hunting rounds safe for my repro 73. It's got a 30 barrel. I load 5.5 trailboss with a 250g bullit for cas. Can I use trailboss for this ? I also have bullseye . Or can you recommend another smokeless powder ?

PS..Deer hunting 50 yards.

Any of the more popular reloading manuals will have loads you are looking for.  I prefer the 17.5 grains of Alliant's 2400 under a 250 grain Lead RNFP cast with 16:1 lead tin alloy.  Or their Unique with a 9.5 grains under the same bullet or a Hornady 260 grain JHP.

  I have a Uberti 1873 in 44 Special, and I've loaded for it and have figgered something out. When I began chronographing loads I'd shoot hem out of my pistols then out of the rifle and compare the velocity. Most loads were with Unique in velocity from the pistol (4 3/4") to the rifle (20")were around 150 - 200 fps, but with AL2400 and W296/H110 the gains were up near 300 fps as the slower burning powder was optimized in the longer rifle barrel. I wound up achieving over 1400 fps with a 260 gr. SWC in my 20" .44 Special and figured that was good enough.

 So, I'd suggest using really slow burning pistol powders. Since the 1873 is also chambered in .357 and .44 Magnum, I didn't worry a whole lot about overloading it with normal pistol loads.

I would not use Ruger level loads for .45 Colt chambered 1873 Winchester replicas, even with modern steel it is a weaker 19th century design.  Stay in SAAMI level standard pressure loads.
