RE: Omega +777= CRUD!
You might also try some Pinnicle powder. I think cayugad has had some excellent results with it. I can't remember how many shots he had before swabbing, but it was alot. As mentioned there is also APP and Blackmag3powders. Some guns don't like the APP fffg powder. I haven't heard of many problems with the APP ffg. You will just have to try different things and see what your gun likes. Ihaven't heard of any crud ring problems withPinnicle, APP, and Blackmag3 powders. I have a lot of 777 ffg, so I will be swabbing between shots until I use it up. Thinking about joining one of the local gun clubs so I can have access when everybody and their brother isn't there!! Maybe I can use it up quicker then!!!
Like KBacon, I have also used the 777 primers and they do seem to help with the crud ring.
