CFE223 Powder

[jerryv]

Has anyone tried CFE223 yet with cast bullets in the 223?

It would be interesting to see what the copper fouling eleminating agent does with any lead fouling.

The agent is either a tin or bismuth compound - but I'd need a chemist to tell me what effect either might have on lead.

I've been shooting ramshot exterminator out of my 223 with jacketed after reading an article by John Barsness about how it cut down on copper buildup. I would have to take another prairie dog trip before I could say one way or another. I can say in my guns it is accurate and cheap.
I have been wanting to work up a cast rifle load with it. I can't find any info on it so I guess I'll just wing it ( something I've done a lot but never really liked it! )
I don't really have any leading issues but I've always had the same question as you.
