What is the life expectancy for a CZ 455 barrel in 22 cal?

A 22lr barrel, should outlast you as long as you don't damage it from excessive, or improper, cleaning..

Roughly 50 rounds short of eternity.   

For .22LR, you're looking at several hundred thousand rounds through any barrel and even then I'd suspect poor cleaning technique to be more of an issue.  I can't reference any scientific study in support, only what I've read.  Add to that, CZ barrels are hammer forged, which supposedly makes them more durable.

I have a Anschutz 54 Sporter from the early 70's that's had thousands upon thousands of rounds through it and still shoots fantastic.  I don't see any reason why a CZ barrel wouldn't last the same as long as you take care of it and don't abuse it with improper cleaning.

Back when I was in college in the early-mid 60's I was on a ROTC smallbore rifle team.   We had a bunch of Winchester 52D and Remington 40X rifles that looked old when I started shooting them.  Some of those guns had 400-500 rounds a week fired through them, barrels were never cleaned and the performed very very well on the international  smallbore  50 ft target.
