Just a guess, the 17 hmr definitely went kaput a bit north of 12k. Guessing based off of bore diameter to volume, and the fact that shot strings are close to together.
Granted the 17hmr got burnt out when ammo was sub 7$ normal price. 10k of my hm2 was sub 4$ blowout priced, at 7-8 a 50 it slows my roll a bit.
Don't know for certain when the barrel will go, it's just that the current barrel has no replacement available.
