So it has been awhile but I was thinking about something that I heard a gunsmith say once. He was saying that he took a sporter barrel and took a piece of aluminum tubing and slipped it over the barrel all the way down to the receiver. After this he filled the inside of the tubing around the barrel with some type of an epoxy. In some sense making it a heavy contour barrel. I'm certainly not saying that I am going to do this. I was just curious if anyone here had ever heard of this or how it might affect the accuracy of the gun? Thanks guys!
 
It's been done. I've had a few in my shop. There was a gunsmith somewhere in gunsmith neverland that was building stupid, stupid lightweight mountain rifles like this. I mean a long action magnum weighing less than 4.5lbs.

The barrel was a piece of spaghetti. It had an alloy sleeve fitted over it and then basically the factory M700 Titanium action became a victim of the drill press. Holes everywhere. The buttplate was a piece of roll cage foam with a slab of thin leather glued to it. There was no forend on the stock. It was sawed off right in front of the recoil lug.

It was a very, very purpose driven rifle idea. -Destined to literally fall apart after just a few hundred rounds too.
 
I think it would likely stiffen the barrel but at the same time insulate it causing heat issues faster.
you can get a very thin barrel to shoot very well you just have to understand that it can start to walk after it gets hot.
I was a big fan of the carbon barrel idea , had a couple earlier ABS , i had Rock flute the hell out of a 30 cal barrel to reduce weight and in the end i'f found going with a lighter conture makes sense and general losing a couple inches of barrel length doesn't effect velocity enough to be concerned with.
Now if i were building a varmint gun that may see longer strings of fire i'd probably go with a heavier barrel and have it fluted
 
I'm not saying that I would do this, I just was curious if anyone had any reason to do this? I believe the reasoning for this smith to do this was to give the barrel a heavier looking contour instead of re-barreling the gun. I was thinking of doing a "project .22" that I have; however, I believe I will just stick with the correct method and just re-barrel the .22 instead. Just wanted some of the thoughts of the more experienced members here on the Hide.

4.5 lb action in long action magnum flavor?

Normally people pay women clad in black leather with whips and chains to be abused that badly.

I was told by an old shooter once that this was common practice in the early days of benchrest. He said they would actually run the sleeve all of the way back over the action and drill & tap it.
 
I don't think he meant a tensioned barrel. ^^^ That is very interesting, I figured the idea came from years ago, but never would have thought that it might have originated with bench shooters!
