I notice it coats the bore with a white powder that comes right off and doesn't seem to build up. Anyhow about the only stuff I shoot nowadays is Triple Se7en and GOEX 3F. I keep giving away pounds of RS and I still have 4 of them. I should use some of it to break in my new cheap $109 inline the name of it escapes me right now. Oh that's right it's an Omega.

(Sorry Cayugad lol)
