keep your barrel clean, particulates in the barrel + BB's will cause some degredation, regardless of the type of BB used.

clean BB's + Clean barrel = absolute minimum of wear. (i would almost say 'no wear' but i know the engineers of this board will point out the impossibility of that unless we've developed frictionless surfaces )

bear in mind that BB's don't normally touch the barrel wall (should ride in an 'envelope' of air)

Correct me if I'm wrong, but the BBs doesn't touch the barrel. The BB is surrounded by air.

the bbs can bounce around the inner barrel. that is what systema made a 6.04mm inner barrel. its supposed to have the ideal amount of bounce/accuracy ratio.

there was a thread on it somewhere here.

Check out the picture here: Tanio Koba Twist Barrel (For VSR) - Zero In : Airsoft Forums
It shows how the BB bounces inside the barrel going from left to right. Again, this is theoretical.
I think an easy enough way to check this would be with a microscope. Check the BB before it's shot and after (catch the BB with a net or something) and if there are tiny scratches on the BB after it was fired, most probably, it left tiny scratches in the barrel. And after 10 thousand shots, it will add up to a more or less ruined barrel.

While I believe there is BB contact during firing, I think it would take allot more than 10000 rounds to wear the barrel to a point where there would a detectable performance change.

BB Bastard is going to be testing this theory soon. We have just settled on a testing method and are sourcing the barrels and cameras required.

Can't wait for the results. I'm really hoping they are positive and that I don't have to buy a new barrel every year. (Even then, I don't think it's going to stop me from using them)

Be sure to test with barrels of different material, such as stock brass, aluminum (ex, Madbull), and stainless steel barrels.

Thanks for the testing!
