Time will tell, but precision rifle barrels where the user is expecting accuracy and reasonable barrel longevity it will be a challenge. Someone looking for .5 MOA over 3500 rounds out of a match grade barrel is probably not going to be a happy camper when the .277 loaded to 80K PSI cuts that .5 MOA life in half and the barrel is shooting 1.25 MOA at the 3500 round mark.

For military applications where up to 4 MOA is acceptable it’s not as much of an issue if over the course of 10K rounds a chrome lined rack grade barrel goes from 1.5 MOA capable to 4 MOA.
