.45-60 in a Walker Conversion?

[H. K. Uriah, SASS #74619]

Here's an odd qeustion.

If you have a .45 Colt conversion cylinder for a reproduction Walker and you were to ream the cylinders to fit, and enlarge the bore to .458", could said pistol handle .45-60?

There looks to be enough room for everything to "fit."
I know there is no real reason to DO this, especially considering the existence of .45 BPM, I am just wondering if it's possible.

I think Hovey Smith deepened the chambers to take 460 S&W Magnum case.

I have given away .460 cases to a couple people for this purpose.

At least ONCE.  After that . . . . .

Found this.

Yeah, that's .460 BPM.  (Black Powder Magnum)

I wondering about other esoteric "possibilities."

probably wouldn't even have to bother with this step. 

 

I expect a soft .454" bullet would work just fine...all things considered.

 

YMMV  😊

Well, I got out my cartridge measuring caliper thingee and started doing some measurements.  While there might be enough room to make the chambers bigger, the rim is a bit too large to fit.   So in other words, it wouldn't work.

I suppose the other option of just lengthening the chambers for the .45 BPM would be a proven course of action, but I doubt I will do so.  

This really was just a bizarre notion from the get go!

What can I say?   I find it amusing to talk about highly speculative ideas.   Even if nothing comes of them, they can be entertaining.

H.K. !!  Yep.  Quite entertaining.   Kkeekp up the good work!!

How about using a 410?

Load it with a 45 bullet.

Grand Father used to shoot 410 out of a Trap Door.

You can do most anything if you want to spent the $$$$. When I started CAS I bought a 94 Trapper 45 colt. Of course it comes up one round short in most stages. I looked into having it converted to a 20 inch carbine. I did find one place in Montana that would do it for a cool $1000. . Ended up buying a 73 from Cabelas for about $800.
