I'm runnign low on powder and my wife is going into town tomorrow. Shooting a Knight T-Bolt with RS, Shockwave Bonded 250s and TMZ Expander 250's shoots pretty good, but I was wondering what is the best / most consistent powder? I also picked up some 240 & 300 grain XTPs that I havent had the chance to shoot yet, as well as some 250 Shockwave non bonded. Should I stick with the RS? or try Select, 777, JSG? Also what about fffg instead of ffg? Any advice appreciated. Thanks,

Holley
