Fouling problems..204 Ruger...help

Tac 20:

The point you are missing from the link when you mentioned cleaning is necessary after just 35 rounds is what Dtech pointed out to you about copper on the driving edges of the lands.

In spite of the best commercial advice you received, no product is 100% reliable, Moly-fusion or any other. If you take the attitude that no copper is forming, one of these days you will have a real copper problem.

I have found Montana Extreme and even Butch's Bore Shine to do better on copper than Shooters' Choice. But, that's just my experience....possibly yours has been different.

However, as was stated also in the earlier thread, having to clean a Tac 20 after just 35 rounds due to poor accuracy/fouling is not normal. At least not in the one's I own or others I know about. And that is with naked bullets.

As I pointed out then, folks are doing better than that with factory barrels on 204 Rugers.

Good shooting to ya' - BCB
 
The ring on the boltface is a "gas-cut" from gasses escaping around the primer before it seals. This can be from a lot of firing normal rounds over time, OR from too hot loads that are building a lot of pressure and getting leakage around the primer either heavily prior to sealing, or from forcing it around the sealed primer as well as getting worse as primer pockets start to loosen.

A gas cut ring before the gun has been fired many hundreds of times is IMHO a sign to back off a bit, or check headspace of loaded rounds.
 
The ring did come from a hair too much head space, I was just wondering if I might need another bolt someday. The blown primers were about 3 years ago, not causing any problems that I can see, now.
If I was getting any copper there would be a slight green stain on the cleaning rag, wouldn't there? All other cleanings on this rifle before Moly-fusion, and others showed a green stain, a large green stain.
Have you looked into the Moly-fusion website? It is not the product that some bullets are coated with, it is a completely different product. It is so slippery that you cannot get it in the chamber, the bolt will blow out. Johnathon from M-f said it becomes part of the steel in the molicular stage, (I bet I spelled that wrong).T.20
 
Tac:

Yes, I am familar with Moly-Fusion. No mystery involved on my part.

Yes. The copper will show up as a greenish-blue stain as you described...if you're getting it out with your cleaning procedure.

Again, I've found copper removers that work better for me than Shooter's Choice. YMMV
