Rolling Block barrel

[cumminsnut76]

:castmine:My girlfriends dad has a rolling block action that he is looking for a barrel for. I am wonderin where would be the best place to get one of these for a descent price in descent condition. I believe that it was previously a bp 45-70

Numerich has lots of BP barrels in faster twist.
Good luck with that project.

Be aware that the Rolling Block action is a blach powder action and any charges should be held to black powder pressures. Make sure he knows this. Green Mountain makes some barrels that would be great for this action. The price is right and they win prizes for accuracy.

What cal is he looking for? I have an 1889 8MM Swede roller barrel that I'm getting ready to offer up for sale. Threads are 12 TPI square.

The folks with 7x57 Mauser chambered Rollers will be a little surprised about this.
The late models were quite strong and were tested and build for smokeless ammo.
Number 5 is what they are called if my mind is working well today.
A buddy did one in 30-06 for cast boolits and even shot some factory j-words with NO apparent change in headspace. When he sold it I was short on cash or it would be mine.

I have a #5 rolling block as well as a couple of #1's. The 7X57 cartridge of yore was not he same pressure as modern ones. To chamber a #5 IN .30-06 is, in a word, irresponsable. Undoubtably such a combination would hold up for a while but when will it let go? The #5 action is, after all, just a reworked black powder action.

Good morning
I remember reading an article some years ago where Ken Waters dealt with BOLT THRUST rather than just pressure. I think that is the real importance with any rifle.
A .223 running at 52,000cup is no effort for a rolling block. But put a 50-110 in that same action with a 700 grain boolit and a full charge of BP and you better have some good Roller pins in that frame.
Granted the #1 or 1 1/2 frames are limited by the metal strength and best regulated to safe loads. The #5 action certainly withstood the 7x57 loads of early 1900´s without any stretching. I would think a modern made Roller of up to date meturlagy is capable of most any non magnum cartrige. Again bolt thrust of a 45-70 loaded with a 500 grainer at 1800 + fps far exceeds anything a 7x57 does to strain an action.
So bottom line.. what action is going to be rebarreled ? Big difference between a #5 and a #2 Roller action.

I seem to remember an article in the American rifleman about 50 years ago showing how to make a roling block into a pistol with a 30-06 chamber to use as a handy trapline gun. It stuck in my mind because I was a teenager at the time and I thought it was the coolest thing since sliced bread.

sounds very interesting

Post an add at the American Single Shot Rifle Association web site forum classified section. I see them coming up there all the time.

Ok Thanks Lawnjockey

If it were me I would stick with black powder pressure.
When I shoot my rolling block rifle I am fully aware that my eye is in direct line with the bore. What happens if ---------?

Life is good

Thought I would throw a few numbers up here to give an idea of bolt thrust or pounds of force on the bolt face. Using SAMMI specs to figure from this is what I came up with.
45-70 = 5,495
30-30 = 5,829
444 = 7,629
7MM = 8,862
30-06 = 10,404

I have heard from several different sources that Remington chambered the 1902 (#5) action in 30-03 and 30-06 but that doesn't mean I would want one in that caliber. I prefer to stick to rimmed cartridges with black powder pressures.

I own a #5 7x57 . This caliber (smokeless) and rifle were manufactured for export to the south american countries....
I believe the original 7x57 Mauser round was rated at a pressure of 45,000 psi- 49,000 psi, and since alot of surplus military rifles, Mauser and Rolling Blocks, are around the load data stays within that pressure range.
Although I occasionally J's most of my shooting with the RB is done with cast...a big limitation is the poor military sight....so I consider it good shooting at the 50 to 75 yard range.
One of the biggest concerns I have about the RB action is the fact that there is NO gas shield to redirect the gasses which have not been sealed by the case/chamber, bullet/bore. Gases not sealed go back through the firing pin hole !! which is about in a direct line with a shooters eye.
So for me the big concern is to develop a load which will seal the chamber, which alot of reduced loads wont do. The other thing I make sure of is that the firing pin has a correct fit in the rolling block.
