Personally I do not use any anti-sieze any longer - just teflon. But, back in the day when I thought I was suppose to I did try several different types of anti-sieze. Some of them with copper, some of them with aluminum - I would really stay away from them on the breech plug. You can end up shooting some of the anti-sieze with metal intothe barrel and the throat of the breech. The barrel will have copper particles blown into it. Do not think it hurts anything much, other than a stain but it is a bear to get the stain out. It would be my suggestion if you are gonna use anti-sieze - not use use a product with metal particles included.

Just my thoughts...
