What accuracy do they get after 15,000 rounds?

Who are they?

Tubb himself claims match accuracy is maintained that long. Guys were experimenting with very shallow throat angles (Harold Vaughn, for one) of 0.75° for a time and claimed it was good for accuracy, and it appears to me from Tubb's cutaway photos, that the Throat Maintenance System may turn a worn throat into one resembling those shallow angle throats. Tubb says he does get other match shooters to test his stuff, but I don't recall who may have tested his Final Finish and Throat Maintenance Systems, if I ever knew. He may mention names in some of his YouTube videos.

I have used the Tubb System to break in a barrel, makes for a quick 10 round breakin. Never used it for restoring one, I may have to try it this fall on a .223 that is getting long in the tooth, err throat
