I may have to try some of that T7,I havent yet cause I didnt want to fool with thecrud ring.right now I'm shooting pyro RS. I was wanting to try something else but around here theres not much selection, its eitherT7 or pyrodex. One day next week I'll shoot my CVA with the NoEx's to see whatI come up withthere. If it groups good the 1st outing and falls off the next,I'm thinking it may have something to do with the borebutter
