Any Use For An Old Rifle Barrel?

Few years ago I saw what looked to be several rifle barrels in the mud at a friends house. He said, " Yes those are rifle barrels, they were all that is left after a house fire. Take them if you want". I did and still have no idea of what to do with them . They are benchrest calibers, not sure what but if anyone is truly interested I'll go out and look.

I did polish one and it came out mirror finish. Looks like chrome moly . People more knowing than me warned me not to use them to build a rifle because they could burst because they had been annealed by the heat.

Comments?

I think I found an entirely different use for it: two different experiments. First- get some cheap brass. A brand that reloaders would rather avoid. Something with a reputation for not lasting very many loadings. Split into two batches; one that gets the case necks annealed after every shot and one that does not. See how much of a difference annealing makes.

Next- develop a way to cool the barrel that does not involve something wacky like pouring water on it. The application would be for plinkers or varmint hunters. Basically anyone who runs enough rounds through it to really heat up the barrel.

I know, a lot of people cool a barrel with water. I would not want to take a chance that it would cool unevenly and get a permanent warp.

One shot

now your on the right track ... have fun with it and save the other uses for after you have shot it out .

i think you'll find the 7mm rem mag to be a fine candidate for testing things like case annealing and barrel cooling .
the first brand of cases you'll find reloaders avoiding is federal ,... in this case i'd avoid them as well . most people find that the primer pockets geet loose in them long before any other failures occur
