I was very happy to recieve my second 4140 sharps heavy barrel form Green Mt. today until I saw it run in the lathe. We Have a setup where we run the barrel through the headstock and line up both ends. We threaded it and fitted it to a no.#5 rolling block action. When we sighted down the barrel just to see how the weight of the barrel was going to feel you could clearly see that the barrel was badly bowed. When you run it between centers it looks pityful. Sure hope they take this one back.
I'll let you know what happens when they open next tuesday.

I sure they will majke good and take it back. Green Mt is a great co and they make great barrels. Check my post on the 45/70 Rolling Block I just posted that was shot with a Green MT barrel and a # 5 Remington RB action. Jim

Sent barrel back to GM today. They said they would straighten it or replace it, That's good enough. Good honest people .

Sounds good!! I am impressed with Green Mountain Barrels I have one on my Roller and one on my 54 cal side lock percussion ( Round ball barrel in in 70 or 72 I cannot remember exactlly) and a fast twist barrel made by Green Mountain that I got on a clearance that was a made for knight barrel 54 cal made by Green Mountain for a switch barrel gun they made ( not a GM) . ( Knight) I got the rifle barrel and a 12 guage shotgun barrel for 60 bucks. Yep 30 bucks a pop and they still had the 180 dollar price tags on them. My gunsmith redid the breech plugs so I could put a tang on them that I made and drilled and tapped the barrels for a nipple under the barrel for a underhammer set up which I am working on now. Both barrels are getting stocks so I will have 2 guns instead of 1 switch barrel gun. Yep I love those Green Mountain barrels. Jim

I rebarreled my original Ballard #4 with a GM barrel, and it's one of the most accurate single shots I own!

This is my first experience with Rolling blocks except for the .22 cal. My other GM barrel was put on my #5 remington action and yesterday I shot a group , 4 shots at 100 yds, that measured 3/4 wide and 1" high. It a 45/70. Yesterday I ordered a lee mold for the hollow base 405 bullet. This will be my first attempt at casting. My oldest son and myself are going to give it a try and I can't wait for it to arrive.

I tumblelubed those bullets using the Lee Liquid Alox and it worked great no leading. I do get some yellow smoke from the lube when I open the breech but no leading and thats what counts. Good bullet I think you will like it. You should be able to use the lower part of the 1886 loadings with out no problems. Thats what Steve Garbe of SPG lube fame told me and I would trust his judgement on that. OF course that is only with the # 5 action since it was made for smokeless. All the Iron cast black powder frames should stick to the trapdoor loadings. Even though I could push mine a bit more I am satisfied to stay with the lower third of the 1886 loadings. No sense pounding me or the gun. Jim

I had an interesting encounter with a fellow last week.

He stated that many years ago, he bought a used original Remington Rolling Block rifle rebarreled to .45-70. He fired Ruger Number One level handloads after being told that the previous chambering was .458 Winchester Magnum and would be okay. The action blew up, the barrel split, and he sustained injuries to his cheek and hand.

When he went back to the seller, he was told that he had double-loaded the cartridges and that the rifle shot just fine with .458 WM loads.

I am trying, for the life of me, to conceive of anyone ignorant enough to make such a rifle and to fire such loads. Anyone ever heard of similar incidents?

I recieved the bent barrel from GM yesterday. They straightened and stress relieved it. My son and myself chambered it and finished fitting it to the No# rolling block last night and shot it today and it looks like it's going to be just fine. Will I buy from Green Mountain again. Yes I sure will. Great people to deal with. :grin:

JCP,
Sounds great! GM is a class operation, and it's a typical example of why they're so busy!
John,
That's about as bad as I've ever heard for stupid chamberings in a Roller! Even a modern Rolling Block should never be chambered for .458, let alone a 100+ year old gun. I've seen a few chambered for other modern calibers that scare me too. Like one in .30-06!
The Rolling Block is a fine action, and stronger than some, weaker than others. Traditionally this action has always been safe with rimmed cartridges, and a small number of rimless calibers, but I'd stay away from any cartridge that develops pressures of 30,000 or more! Even in modern guns, the .458 developes muzzle energy of nearly double the .45-70 modern loads! A good stout .45-70 load is around 2500 ft lbs of energy, while a .458 Mag. runs 4500-4800 energy! That's a lot of chamber pressure!
