I have found so many things that say do not think about this stuff.
sounds like you are doing ok and I have nothing to loose on a 243 and
7.62x39 rossi and I think I will give these a try and see if they will help.
thanks for your info post.

I wanted to share my recent experience with the David Tubb’s Final Bore Finish System, a fire lapping, 50 bullet system with five groups of varying polishing compounds impregnated into the bearing surface of the bullets. Reloaded with the starting load listed for any powder. Clean the barrel removing as much of the copper as possible. Shoot 10 rounds beginning with the coarsest first. Clean well. Shoot the next 10 rounds, etc. The cleaning does get easier with each 10 shot group.

I watched a friend use the pre-loaded 20-round system by David Tubb’s which uses the last 2 compounds. He was impressed with the improvement and convinced me to try it. I opted for the reloading package which has 5 compounds. I prefer to reload whenever I can! To date I have applied the Tubb’s system to 10 of my Encore barrels; 7.5x55, 30-06, 7mm08, 7mmBR, 270, 6.8, 6.5x284, 243, 6 Rem and this last go around, the 300 Win Mag. I noticed a dramatic improvement with each caliber. The 7mm-08 was just sitting in the safe because I could not find a bullet that would shoot well. After the Tubb’s treatment, I got my 140 Nosler Partition bullets to group 1.5 inches at 100 yds; enough for a successful Mule Deer hunt in November.

When I decided to work up the 300 Win Mag, I realized I had no proof of the change in performance. This time I shot 4 rounds of regular reloaded 180 Nosler Partitions and saved the target showing the string of holes. I went through the Tubb’s program and today I test fired the rifle using the same reloaded batch of Noslers. The results are obvious in the attached photo.

I highly recommend the David Tubb’s Final Finish System. My next project is the 375 H&H!

This is really a testament to how poorly T/C barrels are made. I hope I do not have accuracy problems with my new ProHunter. Tubb's Final Finish is a controversial product. In almost every case, the use of this product will push the throat back which is rarely desirable. However, you obviously have enjoyed a positive response in your barrels. I'll keep this stuff in mind if I have a problem with my new barrel(s).

Thanks for the report.

encore3006,

I have an unrelated question.  You have a 7.5x55 Swiss Barrel?  I have one also, but my encore will not reliably light GP11 Military ammo or mine loaded with CCI LR primers.  Any comments?  Is it the bolt not locking up or do I just need a heavier hammer spring?

I don't know a lot about firelapping, as I haven't done it. I have heard both good and bad, but more good.
I don't think TC puts out bad barrels on purpose and every mfg'r has lemons. They are production (hunting) guns, not match grade. And overall, I think there quality is acceptable, if not more so.
I can't really see whereas firelapping would be all that detrimental to the throat and leade. If it alters it much, I would be surprised if it measured more than by microns, at the very worst a few .0001" of an inch. To me this would equate to maybe the equivalent of normal throat erosion a few hundred rounds(maybe). If it results in better accuracy and less cleaning time, I would be all for if I had a barrel I thought it needed sucha treatment.
I don't know David Tubb all that well, but have talked with him on the phone a number times. My general impression of him,,,,he's all about accuracy, and I don't see him as a "gimmick" type at all. If he feels this method can help questionable barrels, I would trust him.
But all this is the reason I go with custom match grade barrels. To me it's  worth the couple hundred extra to eliminate such frustrations.  It all boils down to what your expectations, needs, and goals are.

Just my 2 cents worth.

Controversial as it may be, the Tubbs system often (not always, though) works well with factory TC barrels that are either picky or poor shooters as much of the time, part of the problem can be attributed to the lack of an actual leade in the barrel.

TC simply goes from chamber to an abrupt beginning of the rifling. Some barrels shoot surprisingly well as-is, but others need some coaxing.

Extended shooting will accomplish the same. But if you have to invest that much time and ammo just to get a barrel to display "acceptable" accuracy, you are often better off going with a true custom.

The ProHunter barrels, as a whole, offer better accuracy potential since each is bench-tested before being shipped. I have a 28" SS Pro Hunter is .308 WCF that consistently prints impressive 200 and 300-yard groups. Its accuracy can't compete with my customs, but there is nothing wrong with consistent 1 1/4 to 1  3/8th groups at 200 yards.

Those kind of groups will kill you a groundhog, coyote, deer, and anything else.....'cept maybe a crow (and that's a maybe) at that yardage. I agree that the custom barrels will more than likely out perform the factory (not always....but most times) but then you are right...most guys buy these for hunting...and with those groups.....well.....who eats crow anyway? (I'm talking actually eating it....not in the intellectual sense).
