I have a RPR that has just south of 3K rounds through it. Most of those rounds have been put through it in large strings of fire where the barrel has very little time to cool (prairie dog hunting). I do clean the barrel thoroughly afterwards, but what kind of life can I expect out of a CHF barrel that sees quite a bit of high-volume use?

I've never heard of anyone wearing out a .17 HMR barrel.

But its a copper jacketed bullet at 2,500 fps so I guess it's possible.

Keep shooting and let us know how long it lasts.

Just going by velocity and powder charge it should last to at least 10k rounds.  But shooting it glowing hot is going to cut some off that.  A 308 barrel will last 5 k rounda and 17 is lower powder pressure and lower velocity

I would guess it's fairly tough to wear out a 17hmr.

I would say it's easier to wear out than a .22 LR or .22 Mag.

There is a thread from 2003, when the .17 HMR was still pretty new, that folks are claiming accuracy drops off a little after 13,000 rounds, but still accurate enough to shoot ground squirrels at 17,000 rounds.  I know match grade .22 LR rifles will do 100K rounds and still be shooting just fine.
