[QUOTE="Frog4aday, post: 1830999, member: 9308"] The final finish will 'polish' down the machining marks, making the path for the bullet smoother, reducing fouling and often improving accuracy (though they don't make that claim as part of the product promotion, which is logical. It DID improve the accuracy of my .308 Win though...) As for "add to bore wear", every round a person fires through the gun adds to the bore wear. Here is the correlation I see when I consider this subject - people will fire 200 rounds to 'break in their barrel' (i.e., reach the point it 'speeds up' & cleaning gets much easier.) To then 'worry' about firing 10 to 20 bullets to accomplish the same task in a much shorter period seems illogical to me. If you think about it, Final Finish process produces [B]less[/B] throat and leade damage to accomplish the same barrel break-in process since fewer rounds are fired to get the barrel smoothed out/broken in. That is less powder and heat trying to torch the throat/leade, which seems like a good thing. I know there are people that worry about sending a 'gritty' bullet down the barrel. I'm fine with that. To each his own. But if you have a factory barrel with the kind of machine marks this barrel has, are you really "losing" anything by trying to clean them up/smooth them out when people are suggesting barrel replacement anyway? Having broken in factory mass produced barrels both ways, I'll go with the Tubb FinalFinish process every time now. It is faster, easier, and accuracy and speed seems to pick up well before the 'normal' 200 round point. That saves me powder, primer, and bullet 'waste' to accomplish the same thing the 'old' way. You can actually feel the barrel getting smoother and smoother as you clean it during the FinalFinish firing process. Stop firing when YOU feel it is 'good enough'. No one says you have to fire all the bullets in the kit if you feel it has worked to your satisfaction after, say, 10 rounds.
