By once a year I mean 1.5K rounds (.223) - heavy profile Kriegers, TruFlite's, Broughton's, Archers, MADDCO's, for F-Class (Bartlein didn't exist back then).
Sure, those barrels will keep on shooting well but it all depends on your definition of accuracy. Truth be known we were only really competitive during the first 300 rounds. Guys called it the 'Golden Age' of a barrel.
I take back my earlier claim to never seen a Proof. I was watching an Accuracy International AXMC in 300WM being zeroed at 100M not long ago. It had a carbon fibre barrel with brake and I assumed until now the barrel was proprietary to AI. On their website it states Proof barrels are used. They were having all sorts of trouble trying to get a group but to be fair it could have been anything, including the two dudes who are more sales-reps than shooters. It wasn't the true potential of that gun for sure, so no claim or disrespect to Proof.
