Tubb's final finish

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.
 
Does anyone have experience using this product to break-in a barrel to improve accuracy.

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
