The barrel life will be many thousand rounds, so unless you are spectacularly poor at load development and sighting in then barrel life shouldn't be a problem!

It’s only burning 11-13gr of powder so barrel heating/firecracking in the throat won't be a big problem like with big capacity overbore rounds

Youd be surprised.. reports are of very low barrel heat, I can tell you first from my .22 TCM that this is the case. Even firing 20 or 30 rounds in quick chrono sessions the barrel is barely warm to the touch. The suppressor has yet to get hot.
Other than general bore wear from friction I dont think throat flame erosion will be an issue in the TCM.
Id say the 17 TCM will run parallels with the .17 hornet much like the .22TCM does with 22 hornet.
