I want to give Universal a try too as TXGunNut suggested - as soon as I purchase some. I don't have any experience with Unique and that wieght bullet but I shot a batch of Ranch Dog 290s and my best accuracy was with 8.9gr of Unique. 10 rd avg velocity was 1119fps. No adverse indication seen or felt and the groups were under one inch at 50yds. Would hope to do better but the Unique performed as well or better than 2400 and 4227, at least that trip.
