Re: Aluminum Sleeved Barrels
I have thought about this in the past as others have. What might be the problem is the steel barrel will heat up pretty fast and the alum sleve will suck the heat from it, good thing yes. Bad thing will be the alum growing and contracting through out this process, how much i dont know.
If it were tensioned or not barrel movment may become an issue. It would be similar to a regular
barrel that was not stress relieved properly, they are not accurate. Im not saying it wouldnt work, i just havent seen any facts or research on it. I can see where it would work on 22lr type
rifles where heating would not be a big issue. I would check with a metalurgist and see what
the dynamics are of the alum in heat transfer and elongation. Its gonna get hot, carbon barrels get hot but the material is stable, metal is another story.
Best thing is to try it and do all the tests, then if it works you will have somthing to talk about.
