45 LC loads in a 454 Casull case?

[Old colt]

I was wondering if anyone has done this so I don't need two different brass types around?

When I was looking for a .454 it was suggested that I could do that very thing.

The only way I could get decent results with reduced loads in 454 cases was to use small PISTOL primers in place of the normal small rifle primers. 18-20 grains of 2400 under a 250 gr swc shot well out of my FA83.

Depending on the bullet weight, Titegroup may be just the thing.

Read an article some years back about trimming 454 brass back to 45 LC length for a stronger case to handle stiffer "J" bullet loads. I trimmed back 50 cases to try this idea for cases with a stronger head and web section. I got side lined by some bad medical problems and never got around to trying them out.Robert

I have cut 454 down, at the time it was simply lack of choice, I could not find any 45 colt brass. But that is generally the weak link in the 45 colt is the case vs the gun, plus the 454 will last alot longer. I do not use them in my pistols, probably wouldn't like the rifle primers. And don't load that heavy. But I use them in a single shot, bought it as a 44 mag, so not really afraid to load them to max levels or maybe a little more. Only thing I use in it currently are the spitzer 300gr bullets you get with muzzle loader sabots.

For the OP you can simply use the regular 45 colt data, only issue you tend to run into is its based on the capacity of a 45 colt, pressure and velocity will drop in a larger case. So a max load in 45 colt is a mid range load in 454 case. If your looking for just plinking ammo, works fine.

Yes, it can be done, and I do it all the time. Naturally you will get lower velocities than the same recipe used in .45 Colt brass.

If you (op) are asking can you create a load in 454 brass that is akin to a 255ish grain bullet running at 800-1000 fps, then yes, very easily. You just need to pick a powder that is suited to the 45 Colt, or mid range 454. Tightgroup works very well, as does HS6. I prefer HS6. Tightgroup does not work as well, if trying to maximize midrange velocity, as in my testing it seems to get a little squirrely.

Neat idea. l was told at my local IHMSA silh field pistol match l could only 45COLT loads in my S&W PC 460 MAGNUM..
l am quite sure the gun could handle the pressure..l just don't know if those half scale silh targets could or my fellow shooters.. Not gonna happen tho. l might wear out my welcome-.(

I have excellent results in my 454 revolvers , using full length 454 cases and primed with small pistol primers, with 8.0 @980 fps to 9.0 grs @1,100 fps of Tightgroup powder with 260 ,275 & 300 gr cast bullets .

I generally start with the load I am using in 45 Colt brass, most of the time with Unique and HS6, I find that 1 or 2 more grains of powder gets the same results as the 45 Colt loads.
