H4895 in 6br?

[Josh11]

What should i start it at, grain wise? I think i will be useing 105s. But should i start at 29 grs or higher?

Hodgdon Reloading Manual, 2008 edition, page 89, for the 107 gr. Sierra, no listing for a 105), shows a starting load of 24.5 and a max of 27.5. If it were me, I'd start at 26.5 and carefully work up.

Frank is correct. QuickLOAD and my own development shows 30 grains H4895 as a max load. Start at least 10% below that and work in 1%,~.3 grain) increments.

Josh,

I am currently shooting 29.5 grains of H4895 with a moly coated 107. Using a small russian magnum primer I'm getting 2912 FPS with no pressure signs. Low ES and SD and great accuracy. Rifle is a 700 action with bushed firing pin and R5 stock. The usual warnings apply, work up to the load carefully, because all rifles and barrels are not the same.

I was thinking of useing moly but i just have a savage factory barrel. Should i go ahead and use it? Also when you use moly, where do you start?

 

[Steve Blair]

Moly will extend your barrel life by up to 20%. Start at the same load as naked bullets. It will take 20-30 rounds to start realizing the benefit.

 

[Josh11]

What do you clean it with and how do you clean it if you shoot moly? and how often? I think somewhere said every 60-80 rounds.

 

[TMiller]

I use Bergers method of cleaning when shooting moly coated bullets. It used to be listed on their website.

From Berger's web site:

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.
