Rolling block project
A customer brought a rolling block in that someone nicely turned into a pistol,(Puzzled, but to each his own). The customer was given the piece and wants to convert it back to a rifle. The 7mm barrel was cut so I have to replace it but the customer would like to go with something modern. I know we are dealing with pressures and he is limited to a handful of options for calibers and loads with todays standards. I have my work cut out for me but figured it would be a challenge, to say the least. Anyone have any experiance with rechambering rolling blocks and suggestions, other than chuck it and get an Encore? If you want to privately respond moschgat@adelphia.net will reach me. Thanks in advance.

Hello the rolling block looks will deceive you It is a simple but very strong action . just about any RIMMED cartridge is the easiest to work with. I hope this was not one of a limited number of factory PISTOL style rolling blocks they are very much sort after. 0 -
.30/30, .30/40, 38/55, .405 win., .444 marlin, .45/70/90/120? + a hole bunch more. if it was originaly a 7mm you can add several rimless carts. also. just keep the chamber pressure to the same specs. as the original 7x57mm (45,000 cup). just make sure you square the breech face with the bore and maybe bush the firing pin hole, also check the breech block and hammer pins for close fit.
i've got a complete trigger guard assy. if you need one0 -
Be nice if you'd post a photo............

I would remove the pistol barrel and pistol grip from the action PRONTO! The feds take a very dim view of long guns that have been converted to handguns, no matter how old they are. Why tempt fate, nobody will hassle you, for just having a Rolling Block Action.

I would'nt remove a darn thing until its ascertained wither or not its a Gunsmith special or an original Model 1871 Remington Single Shot Pistol or maybe a Model 1901 Target, Single Shot Pistol, and lets not forget the 1865 and 1867 Navy Models ...Again lets have a Photo and some information about this Pistol You have in your pocession...If its any of the above....You're looking at some serious Money...

First do a little research and make sure it is not a rolling block pistol. You could destroy a valuable pistol if it is one of them. Remington made them for the US military. For example the 1867 rolling block pistol in 50 cal. for the Navy. And then there is the 1871 rolling block pistol. An example:

The 1891 and 1901 Target pistols in smaller calibers. I am not aware of any 7mm rolling block pistols but within the different south american contracts there might be one. Also if cut down from a rifle, it likely is pre 1899 and thus an antique. If that old it is not a firearm per batf and legal in that configuration.0 -
Quite a long while ago there was an article in a gun magazine
(probably in the sixties)where they showed how to convert one to a pistol. That raised quite a stink at the time but that may have been when it happened. (If it's not an original pistol or maybe done long ago.)
You're not only going to need a new barrel but also some way to attach a stock since as I recall the tang had to be bent to attach
the pistol grip.0 -
Thanks for all the information and thoughts. It was definately a convert from rifle to pistol, and was in fact, apparently done in the 60's. However the tang was bent but not cut. Whomever completed the job did a very nice job! I , in the research was able to ascertain that if one stays under 40,000 PSI pressure, there should be no real concerns. That opens a possiblity for 30/30, 32 special, 30-40 Krag, 7MM, and a couple others. There is also the chance of a 44 Rem Mag or 41 Mag. It would probably be easiest to get an old rolling block barrel and go from there, but yet I could probably find a good take-off barrel and modify. The square threads and intricate chamber cuts are gonna be a fun project. Such a simple gun, and well designed for its time! Having said that I tried to convince the customer to go with something like the Encore for versatility, no dice. 0 -
Great rifles to shoot. I prefer mine original. I shoot one in 12.7x44 with blackpowder. At the Texas C&R Rendesvous recently the guys standing behind me could see my bullet parting the heat waves as it traveled down range. These are strong actions, but they beg for big slow calibers.

If it's a #1, Mod 1902 smokeless action the firing pin hole doesn't have to be bushed. It should have a circular spring extractor that will work for cases in the '06 head size but should only be used for cartridges in the 7mm Mauser pressure range.
To verify the action is as above, the barrel thread is 1.055" od and the shank, 1.000" od.. The black powder frame is .975 and .920" respectively.
Since the tang is nicely bent there is a beautiful pistol grip model rolling block rifle that you might copy.0 -
The 7mm Rolling Block as well as other calibers SPECIFICALLY made for large smokeless powder cartridges were known as Remington "Number 5's".
Had a primo, original condition, #5 rifle in 7mm, years ago. Even with very light smokeless reloads I got incipient failure, ( stretch marks ) on my brass. If your customer intends to reload, he might run into problems.0
