Tom,

I shot one .204 barrel out in around 2000 rounds--but that was when the .204 first came out. I was using it for almost ALL my PD shooting back then, so shot the barrel really hot a LOT.

Have mixed shooting the .204 more with other rounds since then (especially the .17 Hornady Hornet) and barrels have lasted considerably longer.
