Tubb Final Finish or JB bore paste?

[Josh11]

I am wanting to shoot moly coated bullets out of my new factory savage f class. Should i load up some tubb final finish bullets to help with the factory barrel or should i just clean it with jb bore paste? or should i use either one? I really don't know that much on how to clean the moly coated stuff. But i want to use moly for the extra barrel life and pressure. Let me know what you guys think.

I don't know much about shooting moly bullets, but I do not think that is what the tubb final finish product is for. The tubb final finish product is used to fire polish the barrel of your gun, not clean it after shooting. He does have a throat maintenance system that he offers as well, but that is to keep your throat right.
I used the tubb final finish bullets in my .308, and honestly, I wasn't too impressed. The barrel still fouls the same as other guns I have owned. The gun does regularly shoot .5' groups, but I kind of get the feeling it would have done that just as well if I had taken those first 50 shots for practice and load development instead of fire polishing.
I have no experience with jb bore paste.

From Berger's web site FAQ:

Q: Should I shoot Moly Coated bullets?
A: Any shooter who goes through a lot of rounds during a shooting session should use Moly Coated bullets. Moly is a dry lubricant that allows you to shoot more rounds before you have to clean. Since you get less fouling using Moly Coated bullets the accuracy level of your load will last longer within a shooting session. If your load did not shoot without Moly, adding Moly will not make your load shoot. Moly does not eliminate the need to clean your barrel. You just don't have to clean as often. Moly will reduce the pressure of your load, which will result in a slight loss of velocity. In most situations a little more powder can be added to get you right back to the velocity you want to shoot. If you are shooting a compressed load with non-Moly bullets you may not be able to add more powder. It has not been conclusively proven that premium accuracy life of a barrel will be extended using Moly. However, since you don't have to clean as often due to reduced fouling premium accuracy during a particular shooting session does last longer.

Q: If I use Moly Coated bullets how should I clean my barrel?
A: The following is one way to clean when using Moly Coated bullets. It is not likely the only way you can clean if you are using Moly Coated bullets.

1. Push one patch wet with Kroil Oil through the barrel
2. Repeat step 1.
3. Push one dry patch through the barrel.
4. Repeat step 3.
5. Push one patch wet with Butch's Bore Shine through the barrel.
6. Repeat step 5.
7. Let the barrel soak for 5 to 10 minutes.
8. Push one dry patch through the barrel.
9. Repeat step 8.
10. Using short strokes back and forth push one patch wet with USP or JB Bore Paste through the barrel.
11. Push one patch wet with Kroil through the barrel.
12. Repeat step 11 twice.
13. Push one dry patch through the barrel.
14. Repeat step 13 three times.
15. Use bore scope or visually inspect muzzle for copper fouling.
16. If copper is present repeat steps 10 through 15.
17. If you are storing the rifle push one patch wet with quality gun oil through the barrel.

Q: How do I break in a barrel using Moly Coated bullets?
A: Moly Coated bullets will not shoot consistently until a barrel is properly broken in with Moly Coated bullets. Walt Berger has found the following procedure to work best in his barrels.

For a new barrel:
1. Shoot one Moly Coated bullet then clean using the Moly Coated cleaning procedure listed above.
2. Repeat step 1 five times.
3. Shoot three Moly Coated bullets then clean using the Moly Coated cleaning procedure listed above.
4. Repeat step 3 five times.

For a broken in barrel:
1. Thoroughly clean the barrel.
2. Shoot ten Moly Coated bullets then clean using the Moly Coated cleaning procedure listed above.

Your barrel is now ready to shoot Moly Coated bullets.
