    I've used it and would only recommend it if you have issue with your barrel. My .300 wby had accuracy issues but most of all it copper fouled like a pig. It took me close to an hour to clean the bore. Used the tubbs, accuracy improved but most of the fouling is minimal. I would look at TFF as tool, every tool has a use and a place. You must decide if its the right tool. You can also hand lap your barrel instead of fire lapping it.

    Thanx,
    I am unfamiliar with hand lapping (except with my wife). Will check that out.
    Probably posted in wrong forum (newbie). Will post in product review also.

    I didn't use the roughest grit in the 308 kit in my old tikka T3 Varmint. But, I did feel noticeable difference in cleaning the barrel and less fouling. As for accuracy it did help, but I don't think I could quantify the improvement. This did shoot a 5/8" 10 shot 100 yard group with 175SMK and 41.5gr of varget in Winchester brass...so it didn't hurt anything...I keep saying I'll dig up that target and post a pic...

    1: It is near impossible to improve the bore of a quality custom barrel when new.

    2: It is almost always possible to improve factory bores.

    With the above in mind, I am an advocate of TFF for bores that are rough for whatever reason and NOT an advocate of using them in quality barrels.

    I have used them once on a rough barrel. My accuracy did not change at all, which was not bad to begin with. It fouled a bit less and cleaned up MUCH easier.

    I got my guts up and used FF on a long in the tooth put through the ringer Lilja custom barrel. It restored original accuracy.

    I did not use the full treatment. I did not use the roughest bullet group and only half of the others.

    We'll see how long she hangs in there.

    I used the full treatment on an unfired 338 RUM factory barrel. Wished I would have tested it first. It shoots lights out....

    Ive got a stock savage barrel the shot around .75 and then lapped it and its .5 all day and the barrel feels good cleaning like a hart. Also es and sd tighted up. I wouldnt do a lapped barrel with it which would be silly but a stocker or worn down custom heck yeah.

    I wholeheartedly agree with that. I was fortunate to get a tour of the Shilen factory when I bought my last custom barrel. I brought in a factory Model 700 in 7mm Rem Mag for re-barrleing. One of the smiths gave me a look at the bore with one of their high power, high dollar borescope machines. The bore looked like it had been cut with a rusty nail! The tool marks where hideous and deep.

    The next bore we "scoped" was a Shilen Select Match Grade barrel that had been hand lapped. It was as smooth as glass. No tool marks visible at all. If I had not been sold already, I just was.

    I have 2 Kriegers, and one Shilen. I broke all three in exactly like the manufactures recommend. I was easy and they all shoot very very well.

    There is a guy at my range who broke in one of his Hart barrels with the Tubb Final Finish. So far so good according to him. Here is a video interview with barrel maker John Krieger. He talks a a little about maintenance and cleaning near the end.

    I did it with my then new 300 Weatherby Ultra lite. I feel it helped a great deal . Cleaning it was hercky -jerky . Now it cleans in a few swipes . Accuracy has improved and I have confidence in the rifle. If you ever saw an exploded hammer forged barrel , you would agree . They look like wash boards inside. I feel Tubb FF bullets can only improve a new hammer forged barrel. As others have said, you don't have to shoot a full compliment . I feel the smoother a barrel is inside equals harmonic, equals + or - equals accuracy. Thats why the make custom barrels (smooth) .lightbulb
