Now that there is a supply of remington rolling blocks in Canada, does anybody know where I could get a new barrel for a reasonable price here in Canada? Anybody have a preferance as to caliber? I was thinking about .45 Colt for a nice carbine cartridge. Thoughts?

Edited: Got my rolly....now I think that I must buy another one....

.45 Colt would be fun in a baby roller. I would like another in .50/70 or a .50 pistol round with reasonable pressure.
Where is the supply of rolling block actions in Canada?
 
Those Rollers for around $400 look like a good buy, you can get a deep chambered barrel from Douglas for a reasonable price, you will still have to get a smith to install barrel(cut threads, headspace, extractor, etc.)....these are old actions and should be kept to Black Powder pressures, as for calibers...the 45/70 is a good choice as you could use the Trapdoor loads in most reloading manuals, .45 Colt would be a good choice , though it is not an orig. cal., 38/55 would also be a good choice.
 
Just looking at these, this is nice. Looks to me like the original ammo could be loaded with .348 brass too and .502" bullets are easy. I am going to get one at least of those.
 
Just a word of caution; the R in the cartridge designation may mean rimfire; does not mean the gun cannot be converted to centerfire nor that it cannot be shot as is, just that you may find an extra wrinkle to cope with.

To the best of my knowledge, these were all converted to centrefire


From what I'm gleaning from the net, the ones in 8mm were all re-heat treated during the arsenal re-fit for the more powerful cartridge. Lots of resources it seems.

I got mine on order :dancingbanana:
 
I just got a Track of the Wolf catalog in the mail last week, and they had some Green mountain BPCR barrels listed there. Dunno what hassles there may be in getting the barrels in the country, but the prices were reasonable.

Rolling Blocks

I built this BPCR target gun on a Swedish 1873 action a few years ago.
It has a Bauska 32" 1/2 octagon-round barrel in 40-65, and I used pre-inletted Treebone Carving 1/4 sawn black walnut wood, with one of his checkered steel buttplates and steel fore-end Remington style schnabel tip.
The tang sight is from Parts Unknown, and the front sight is a Lyman #17.
It's finished in a slow rust blue and I think it turned out pretty well. It shoots fine, and the only problem is the heavy military trigger pull, which I haven't sorted out yet.

Before I took the original sporterized 12.7 X 44R apart, I slugged the barrel, and as is shown, the rifling is so deep that the slug came out pretty well hexagonal.
It's diameters are 0.4809" to 0.5076".
The rim recess on this barrel measures 0.650" although the books say the rim should be 0.624". The book also says that the 12.7 X 44R has a base diameter of 0.546", and a 50-70 has a diameter of 0.565", but I also found that a new, sized, 50-70 NDFS turned brass case with the rim turned down slightly will chamber fairly easily regardless, and it is only 0.02" too long.
I think I also will have to have one of these new imports, but will leave it in it's original calibre this time.
If it's the same as my other one, I figure I can shoot it using 50-70 brass neck sized only, with a 50-70 425gr. bullet sized down to 0.509", or probably a Lee 50 cal. 320gr.REAL muzzle-loader bullet.
Anyway, it will be a good project, without breaking the bank.
Regards, DaveF.

Bear in mind those BPCR barrels are not proofed for smokeless powder....black powder only...

Huh? Did I miss something? The thread IS about rebarrelling a Rolling Block action, isn't it.
I wouldna thought anyone was about to throw a 460 Weatherby on a Rolling Block Remington action action, but I figure the barrels from Green Mountain will take it better than the action would.

The only barrels that are "proofed" at all in this day and age are some very high dollar handmade British stuff.

The designation as BPCR barrels has more to do with the bore sizes and twist rates than the pressure capabilities, as they are using steel as good as anyones for these barrels (4140, certified, gunbarrel grade) and I figure that with the profiles on offer, they would have a pile more material around the chamber than some, if not most, modern rifles.
But let's stick to the point. No need to worry, it's a rolling block action. It's not going to get a high pressure chambering in any situation.

Trev: Gr. Mtn. did make some barrels of softer metal early on...the price was right and they were meant for BP Cart. but they discontinued them, probably due to litigation concerns....all Green Mtn. Cart. barrels are now made of modern alloys such as 4140,etc....note also that Green Mtn. makes button rifled and cut rifled BP Cart. Barrels...the cut rifled ones are more money but they would be my first choice.
 
Yeah Ben, it was the 4140 cut rifled barrels I was looking at in the catalog.

I was wondering if there are any issues getting barrels for antique rifles shipped into Canada. I should fire an email off at Track of the Wolf and see what they say.

I recently put one of the Track of the Wolf liners in my Rolling Block 50/70. Simple task and we're back to original. Good people to deal with. Mark
