Barrel question.

If I have a barrel that's rifled for .177 lead ammo, what can I ream it for, chambering wise?

Why do you say it's for lead?

I'm guessing because it's a barrel from a pellet rifle

This^^^^^. Fairly heavy barrel too. I just figure I can do something with it.

I think that the first thing to do would be to figure out if the barrel is proofed to handle the pressures generated by a cartridge....

I wouldn't even know how to go about that besides comparing it to other rimfire barrels I have that are also steel. Hmmm.

That would be my concern.

BigDanS

I would not use it for a high pressure cartridge. And the expense to figure out what its strength might be would negate using it over buying a barrel made for it.

Ghost-- If you want to play around and not worry about blowing yourself up, Green Mountain has these unturned blanks you can get for $40-$50....

A pot metal barrel can be "fairly heavy"...

I have taken a couple of pellet rifles apart to salvage the metal

they are kind of uniform thin tube to ream it out for a chamber and a tube within a tube.

Sweet. Thanks Jerm. Takes all the guess work out of it. I'm no gunsmith but I'm sure I can get there through trial and error. Would be better if my old man was still here. He was not only a machinist but also a metallurgist.

I just looked in 3 such barrels and it seemed they had Polygonal rifling. I wonder if that means no high pressure with lead.

Jermanator

Looking around their site, I am not seeing the barrels I am talking about. They have them but they may be out of stock right now. That, and their site is hard to navigate-- root around there long enough and you may find them. I got some .50, 41, .375, and .430 barrels from them for pretty cheap.

Not sure. Said barrel is meant to push a lead pellet at 1200 fps. Of course that doesn't tell anything of pressures in said barrel.

Use plenty of Vaseline or K-Y!

But I will also add, I'm pretty knowledged in metallurgy and the barrel I have is solid steel, no pot metal and not lined by a softer metal. It's steel to the rifling.

True, just ask Taurus owners :jester:

Didn't people used to make zip guns from old car antenna tubes?

There's a reason even the lowly .22 LR barrels are 4-5 times thicker than pellet rifle barrel.
However, I'm not one to cock block a dumb idea. Knock yourself out.:up:

Sweet. They make safety glasses, welders gloves and a face mask for jackasses like me. Only one way to test a shark suit.

ghostsniper1

Btw, my Mosin barrel is about as thick as the .177 barrel in question. Just sayin.

Jermanator

I am not going to say it is a good idea. Or safe. But no matter what you do, get it on video!

Haha. I will. Nothing like going viral on the interwebs. Of course y'all know I'm going to have to make a lower with action to house my barrel? Of course in still waiting for someone to post a link for a reamer in .17 that I can use.

I've used an old pellet rifle with a barrel drilled for a fuse and black powder to launch pellets. The action lasted about oh....2 shots.

Research the rifle from a Beamen pellet rifle and then get back to me.

Is it a Beeman Bear Claw, Elkhorn, Grizzly, Mach 12.5, Predator, Ram XT 51R, R52, Silver Kodiak, Silver Panther, Teton, Teton Gas Ram Air, Wolverine, Zombie, Marksman, or Rebel? They're all a bit different as to barrel dimensions.

And anything under 1/2" diameter is iffy, especially if going with a .17 HMR. Even the little .17 Mach 2 generates more pressure than a .22 LR. Barrel steel in air rifles and barrel steel in rimfire/centerfire rifles are both of steel, but not the same composition/strength. Have fun and don't lose any bits and pieces. The place Jermanator linked has the reamers for the .17 cal. rimfires for rent.

.117 convertible to .22 is where two of the barrels I looked at came from

---

they use an O ring to seal the breach,
so it can't be for high pressure.

Make a barrel liner???Rechamber to.17M-2 Jerm has the best answer.
