I know not too many people have the 45/410 barrel but for those that do i want you to chime in. Basically i just want to know about the set up on the barrel. Is it rifled or smooth? I've got a project that might make this barrel shoot pretyy good if i can figure out the specs on the barrel.

Do they use different steel to make the shotgun barrels versus the rifle barrels?

Thanks for the input i've never actually saw one saw i wasn't for sure. They are pretty hard to find in my area.

I'm thinking since the you can chamber 3" 410 shells the 45 colt is not gonna be that accurate. This has been proven time and time again. Since S&w came out with the 460 S&W why can't you shoot these in the chamber? 45 colts are 1.285" in length, the 454 casull is 1.383" in length and the new 460 S&W is 1.8" in length. Could you shoot either the 460 or 454 and have accuracy increase because the bullet has less distance to travel to engage in the riflings? Or would there be no big increase in accuracy?

Pressure is why.....and not to mention the amount of case thrust involved...check the pressures on those 2 rounds... From Chuck Hawks Web page...

Smith & Wesson has done the obvious by introducing a .45 caliber cartridge for their X-Frame 5-shot revolver. Hornady and Cor-Bon did the cartridge and load development.

The new cartridge is a lengthened version of the .454 Casull, itself a lengthened version of the .45 Long Colt. So both of those cartridges can be fired in a revolver chambered for the .460 Magnum.

The basic dimensions of the new .460 Magnum are as follows: bullet diameter .454", rim diameter .520", case diameter .478", overall case length 1.800", cartridge overall length (COL) 2.300". The official SAAMI maximum average pressure (MAP) is 65,000 psi!
A bit much for the Handi frame( IMHO)...and even though the pressures are down somewhat for the 454...I don't know if you could really load it up to it's potintial...but definatly worth finding out about...

I searching as i type and from what i have found so far the 454 casull is 55,000 cup. Haven't found the 500 or 460 yet.

How much pressure is the 500 S&W producing?

All reloading manuals show max loads to be just over 50kpsi, the S&W handguns cylinders are proofed to 71kpsi, FWIW.

Is this a case of pressure or case thrust that would ground this idea from the get go?

If pressure or case thrust wasn't an issue would this improve the accuracy of the barrel?

Each rifle is different...what may be a max pressure of one...won't on the other...accuracy for either is independent for each as well...what may shoot good at low/high pressure in 1...may not in another...

60.000psi and that large of a case head...on a Handi frame...I don't know...maybe it will work...maybe it won't.....I wouldn't..but that's just me...ya know?

I'm not gonna attempt it right now but if the chance arises i may go after it. Right now i have a brush gun project goin that needs my full attention. i just thought the lengthed case would help the accuracy issue. Could you use the the 460 brass and maybe load it down?
