Aluminum barrel bands?

Got this idea at work. We sit aluminum stock on steel in between grinding passes to act as a heat sink and keep the steel from heating and swelling, which would throw off our numbers. It's very light and apparently it acts as a great way to draw heat from the steel.

I was looking at my Mosin Nagant barrel bands and between the two I had an idea. Would there be any benefit to using relatively long aluminum bands clamped onto the barrel? My thinking is that it could benefit the rifle in two ways that a lot of people talk about with the Mosins: It would help with cooling of the barrel and potentially dampen the barrel harmonics. If it works for one rifle, Id on't see why it wouldn't work for others. Has it been tried before?
 
I havent heard of this, bit I would be concerned about the unequal expansion of the two metals forcing the barrel off its poa
 
Benchresters used to sleeve barrels and actions with aluminum because of aluminum's ability to dampen vibrations well and conduct heat away rapidly. So yes, it works, but no, it is not easy to do it right.
 
I'd either; sporterize a Mosin, free float the barrel and glass bed the action.

or; glass bed it as it is

or; realize I was just trying to polish a ****, and use it to burn through cheap surplus ammo and if I want an accurate rifle, save that money you'd spend and buy something else.

To do it properly you'd have to sink way more money than it'd be worth spending.
 
my stainless Ruger 10-22, actually has an aluminum action, & stainless barrel, & had an aluminum barrel band... I'm sure just because aluminum is cheaper than stainless... I've since customized, but the aluminum band didn't seem to effect the accuracy on the rifle in stock form...
