Does anyone make a long gun in 460 S&W?

For you guys that know ballistics, please answer this: If this round develops 200 grains loads at 2300 FPS in a 7.5" revolver, what would it do with a closed breech 16.5" to 22" rifle?

I didn't check to see if they do, but I'd be surprised if Wild West Guns in Anchorage, AK doesn't already have a lever action in 460 S&W. They did one for the 500 S&W that I saw at Shot Show this past February.

There are none that I have gotten wind of yet, and I stay
abreast of new firearms developments as a hobby. I
would expect some announcements in conjunction with
the upcoming (Feb) shot show, for sure.

I don't know of any, but I've had the passing thought of reboring my .454 1885 High Wall to .460. :) With my .454 rifle (28 inch barrel), I see a 500 fps increase over my .454 revolver (Super Redhawk, 7.5 in. barrel). I would assume you could expect a similar increase in a .460 revolver, but it would depend on a number of factors.

If you were to get a 300-400 fps increase in a .460 carbine vs a revolver, that would make a very good, fast handling brush gun with decent medium range ability. It will be interesting to see what comes out.

I wonder how the rifling would be set up, the revolvers are using gain twist rifling

I'm pretty sure they call it the 45-70 Government...or the .450 Marlin.:) Ballisitcs can't be all that far apart.

What do you suppose the purpose of the gain rifling is? I have a couple ideas that seem valid to me, but I'm curious what everyone else thinks. I figure revolver torque (recoil) and lead bullet usage are two primary reasons, but I don't have any factual information that brings me to those two conclusions.

I am sure torque plays a factor in the gain twist decision, plus in a revolver, you get all that jump between the bullet and the rifling, something going that hard in a straight line and then being expected to twist fast must play heck with everything, starting with a slower twist would eliminate some of that stress

Look at Thompson Center Pro Hunter Encore Katahdin S&W 460 & S&W 500 in 20" rifles . I have a 20" Bullberry S&W 460 mag Encore rifle barrel http://www.bullberry.com

I know that Wild West Guns does work with the Marlin 1894, but I have never heard that they can make it shoot the 460 S&W. H&R Hnadi rifles may have a 460 out. It seems that this one is likely to turn up sooner or later. It would be nice if such a lever cation that would shoot the 460, would also shoot the 45 Colt, but I wonder if that is possible? It seems that if one loaded a heavy long bullet to longer length it might work, otherwise perhaps one could the 454 and if one could obtain brass cheap enough, that would be nice.
The problem, as you are aware is the 1894 action will not take the pressure of either 460 or 454, however it might be possible if one used the 336 action ( not to suggest that action could be designed to accomadate that much pressure), as was used on early 44 magnum.
That would make an interesting lever actrion rifle. Perhaps someone here that is an expert on lever actions has the dope on this?
