I was surprised to discover that the loads listed in my mid-80's Hodgdon manual listed loads for the NAA revolver placed it on par with or beyond the 454 loads of the time. I'm sure you already know this, but they only list bullet weights up to 260gr. Have you experimented with anything heavier...perhaps 300gr or more? Before I order anything I'd like to know if there is enough cylinder length to accommodate those bullets. I just received in the post 400+ factory primed brass. Lee, if you'd like a sack full of 50 to play around with just PM your mailing address to me. Anybody else have experience with this gun?    |

The 450 Express will handle heavier weights, but the problem you run into is bullet jump. Since it headspaces off the neck, you're really limited on hard crimping. BTW, word of warning on these guns. The chambers on every one I've seen are way over-sized. As such, I wouldn't push the loads too hard. 30,000 PSI, "Ruger only" 45 Colt is safe, but I'd shy away from anything near 454 levels. Good luck and definitely let us know how it shoots. I've always had a thing for those NAA Eagles. -Lee www.singleactions.com |

Forgot to ask....how's the trigger on yours? Mine was ridiculously heavy until I did a trigger job. -Lee www.singleactions.com |

Could you theoretically cut rim counterbores in the chambers and use shortened .454 and .45 Colt brass?
That would let you get a hard crimp, and maybe take up some slack on oversized chambers.
Actually doing it might be sacriligious, but I'm just curious.

Yep, that would work. In fact, you can form 450 Express off of 454. I have some that came with my gun done on Casull brass (sized, reduced rim, etc). Definitely would allow for a harder crimp. -Lee www.singleactions.com |

The trigger pull is 4.5 lbs Lee. That's pretty heavy. But, it has no take-up or creep at all. I can live with it.
Before I even received the gun, Aggie, I was wondering the same thing. I'd hate to alter either cylinder in any way, but if what you speculate is realistic and if it would make the gun more useful I'd be willing to sacrifice the 45 WinMag to a skilled machinist capable of doing the work.

The way I was thinking it, the cylinders would remain viable for the original rounds, just with a rim recess. You would trim the .454/.45 to length of .450 mag / .45 win mag. Kinda like running 45 auto rim in a 45 acp.

The trigger pull is 4.5 lbs Lee. That's pretty heavy. Mine was a tad over 6 before I did a trigger job. Like yours though, there wasn't any creep. Keep us posted on how it shoots. There aren't many of us still working with the 450 Express. -Lee www.singleactions.com |
