Being a new member, I have a question. Does T7 3F/ 2F (100 gr, ) loose powder leave a "crud ring" as the T7 pellets do, as I read in this on this web site ? I'd like to thank all of you that will respond to this question in advance for your time and help. I'm currently shooting an older CVA , optima and the newer optima V2 version. In the past, I used Blackhorn 209, now it's to expensive for the average shooter, like me.
