Has anyone used the the G. David Tubb bore polishing system yet on their rifle?

I have never used it, but I have gotten to replace a lot of barrels earlier than they should have needed it because the owner used it. Do yourself a favor and leave the bore finishing to the barrel maker. The exception would be a old or factory barrel that is very rough to begin with. Then you really don't have much to loose.

Ditto gasgunner. I have used them on really rough barrels to smooth them out but only after 100-300 rounds proved things wouldn't get better otherwise.

For all the bad things they do to to throats, I will say that they turned an Adams and Bennett 416 barrel into a pretty good tube for me. How long it lasts remains to be seen.

I thought about trying it on a really rough barrel that I have. I figure that I'd try it then pull the barrel and cut a thread off of the shank and cut a new chamber. That should correct the throat wash out enough, I think.

I don't think modest use will ruin your throat, just shorten its useful life.

David Tubb shoots Schneider barrels...or he used to anyway. I have a couple of Gary's barrels and he does not recommend any lapping beyond that which he does when he makes the barrel for you.

I used it once on one of my dad's rifles. It was the roughest factory barrel I'd ever seen, and it coppered up terribly after only a few rounds. Tubbs system did the trick, but it also lengthened the throat considerably. In my case, that was OK since the chamber was short throated to begin with.

If you don't mind, what make of gun and what caliber was it?

I have an old custom built Enfield from my grandfather that his brother built in the 60's-70's era. It shoots like buck shot at all ranges and it doesn't clean fast. Just thought it might help.

It was one of the original 7-08s in Model 7 with the 18.5" bbl.

I think SST has it down correctly. Most guns will lose throat with polishing using the Tubb system. But, if you do set the barrel back and rechamber, you'll correct that problem. One other thing that isn't often mentioned is that of the crown. Have seen crown damage from people who try and "polish" their barrels with cleaning rods and different grades of polish. Many barrels can be improved by a thorough cleaning and having a smith do a recrowning.

I used it on an 89 Ruger 77 that I had a 24" heavy A&B barrel put on and was rough, did the Tubb kit and had the barrel set back and upgraded to Ackley improved, shot very good and was easy to clean. Would not do it on a top brand barrel.

I've used teh NECCO system and it was a pain in the butt but did a reasonable job BUT it did move the throat...wouldn't use it again.

I've done the Tubbs Final Finish on several barrels and it works great....I did not, however, use the coarser grades but only the finer ones. I used them, per the barrel maker's instruction, to break in the barrels rather than the fire a shot and clean method. Worked like a champ and i did not get any measurable throat movement.

I can't see any use in a new or good barrel but some have reported being able to breathe life back into a dead barrel. It's probably best for restoring a cracked up, rough throat on a high-mileage tube.

Just for S&G's I tried the Wheeler kit (roll your own bullets) in a Remington 76 pumpgun in 30-06. The bore was a terrible fouler and shot lousy besides. I smoothed it up nicely but haven't had time to definitively test the accuracy part. Looks like it'll work and hell, I'm not taking this thing to Camp Perry anyway...

Update on the Rem 76 - after using some parts of the Wheeler kit, it cleans up like a dream! What used to be a copper mine now comes clean with a few patches with NO jacket fouling. Unbelievable.

Accuracy improved marginally, from lousy all the way up to unimpressive. :-(
