I load 12.7x42 centerfire for my great grandfathers Rolling Block.

I was thinking of a companion revolver.

The BFR revolver some in a short cylinder 500 Linebaugh.
I didn’t see 500 Linebaugh Max listed for the long frame cylinder.
I asked and they responded they won’t do one for 50 Alaskan.

The Short Cylinder (Standard Frame) will take a 1.9” OAL.
Long Cylinder frame is good for 3”.
500 linebaugh is about 1.75” OAL, case 1.4”
500 linebaugh max about 2” OAL, case 1.6”
12.17x42 rimfire about 2.04” OAL, case 1.62”
12.7x44R about about 2.25” OAL, case 1.72”
50 Alaskan about 2.4” OAL, case 2.1”

My rolling block was originally 12.17x42 Rimfire.
To shoot my options were have the block redone to center fire, or find a center fire block and fit.
I found a block and fit.

I trim 50 Alaskan to 1.65inch for it.  OAL of 2.0”.

I just assumed I would need a long frame, in 50 Alaskan.



For comparison, 44 mag, 45 colt, and my rolling block ammo.











Thinking more,

My 50 Alaskan Starline brass is 2.1”
I cut it to 1.67 inch
Then quick fine trim and chamfer at 1.65” / 42mm
My OAL Hornady Great Plains 385 grain is right at 2.0 inch.

When Husky converted rimfires to to center fire in the 1800s, some would not quite chamber 44mm brass.
Mine does case right at 44mm but no issue trimming to 42.

So, I could either trim brass about .1 inch more or sear 0.1 inch more- or some combo of the two.
Like an OAL of 1.8” or so, shoot my rolling block ammo in my rifle and also in the 5 shot short frame BFR.
And also real 500 linebaugh out of the pistol if I want.

I tested loads from 600fps to 1100 fps on the old girl and settled on 900fps. No reason to punish her.  My great great First Nations grandfather gave it to my French great grandfather in Quebec when he got there as a dowry for marrying like his fifth daughter.  Ended up with my grandmother and her first husband- then to my oldest uncle.  When her first husband died she remarried a widower and knocked out three more kids and my dad.  Oldest uncle gave the rifle to me before he died.  And also the smooth bore EIC percussion conversion my great grand father got ahold of and had before he got the dowry rolling block.











While sharing case and dimensions-
Keep in mind 500 Linebaugh in a revolver pushes stuff like 525grain bullets to 1100 fps,
Linebaugh Max to 1300 fps.
I don’t know what velocities they get in a 50 Alaskan rifle.
50 Alaskan itself 525s at around 1900fps.
Thats compared to 1500fps out of modern 45-70 525 grain loads.

I’ve never shot one and don’t plan to.  I do want to have a revolver that will shoot my rolling block ammo.

I could get a short frame cylinder BFR five shot in 500 Linebaugh and use my rifle ammo in it.

What other options are out there for 500 Linebaugh and 500 Linebaugh Max?

Good post.  Cool provenance on your rifle.  +8700 internet points

I believe Linebaugh used a converted Ruger in .45 LC for his first 500s.  In theory you could have a custom maker do a conversion for you.

Freedom Arms has a model 83 revolver which is chambered for the 500 Wyoming Express, 475 Linebaugh, 454 Casull or 44 magnum.   The 500 Wyoming Express is supposed to be between a 500 S&W and a 500 AE.  Supposedly the 500 Wyoming Express can handle higher pressures than the 50 AE plus can use a heavy roll crimp.  The 500 Wyoming Express is close in power to the 50 Beowulf and fit in revolvers smaller than the X Frame S&W 500.

I have shot Freedom Arms revolvers in 454 Casull and 475 Linebaugh plus a Desert Eagle in 50 AE.   I have also shot the 500 S&W all with full power loads.

Another interesting revolver is the 45-70 or 50-70 single action revolver developed by Earl Keller in Evansville, Indiana in the 1970’s.    The revolver developed by Earl Keller was sold under the name Century Manufacturing, inc..  I had a chance to visit Earl’s manufacturing operation and later shoot his 45-70 revolver.    The 50-70 might be another option to consider.

I hope you find a solution but I think ultimately your going to be reloading all your ammo.

Yeah, I’ve been seeing pretty limited options.

Zero 50 Alaskan pistols.
Very rare here and there 500 Linebaugh Maximum.
And basically one maker for 500 Linebaugh.

I was just checking to see if there is some big secret Linebaugh club.

It’s seems to have really been eclipsed by the other 500s since.

Best for me will be to trim/seat the rolling block ammo to just under 1.9”, and get a BFR.

Otherwise I’m looking at getting custom work done to an x-frame or something.

BFR will not make the BFR in 50 Alaskan.  They will not make the lone frame/cylinder in 500 Linebaugh like they will a short frame.  Probably because they know people will shot 500 Linebaugh max and 50 Alaskan in it if they did.

This revolver is one the list to get-
But my list also includes an 1873 lever action to short stroke, a pair of SASS vaqueros, an SKB coach gun, and various other limited/hard to fine nonsense.

Yes.
That guy has had a BFR converted and shoots 500 Max and 50 Alaskan.

The Buffalo Bore owner guy has one too I think.

I just want a handgun to pair with the old rolling block.
The closest I can get off the shelf, or at least to custom order, is a BFR in 500 Linebaugh,
And I’ll just have to drop my OAL from 2.0 to under 1.9”.

I have made ammo and only shot the old gun about 50 times.
Even then, the modest recoil is hammering the buttstock and rattling loose the forestock.

It’s 150 year old wood.
When I got it the leather wrap holding on the cut down/previously cracked foresrock was dry and cracking off.  The trade cloth was a tracing paper thick disintegrating into dust layer.





In the decade since then, just being a wall hanger, most of the leather had broken off.

Under the forestock, which is just the front half, the back half must have cracked and been cut off, was a smelly resin/lead block to “fit what used to be the middle of it to now the rear of it.

The military sight has been replaced by a three folding leaf.  A front sling mount had been soldered on the barrel.

I don’t have the right barrel ring, but I do have a much better condition front and rear stock.

Using that would take away the decoration my great great grand father had done and were on it when my great grand father got it.

Some say I should have left it as a wall hanger.

I elected to let it shoot again.

I have an unhealthy desire/fetish for handgun/rifle pairs.
I’m pushing 60, have a ton of other guns, and realistically will maybe take it out once a year and shoot five through it.  There is no practical need for me to have a handgun to go with it.  I just want to.

Your earlier posts were fairly detailed, so I did catch all that.
Just giving a possible option for what (as you know) is a search for something that's going to be very, very uncommon.
Good luck with it.

Lee Martin made a BFR in 50 Alaskan (only one as far as I know). A guy in Germany has as well. They are very large revolvers of course.

Yeah looking into it once you hit 44 mag/full 45 colt-
There a little bump in to 454, 460, some other 500s-
Then once you get to 500S&W magnum and these few it’s a tiny, tiny niche
