i just bought a 700 VSF 221 fireball with the 22in barrel. I picked up a lb of little gun and AA no. 7. These were the only two powders my local store had that i saw was used for this cartridge. I also picked up a box of barnes varmit grenades in the 36 grain. I was wondering if there was anyone out there that would mind sharing some info on some good loads that i could try out to get me started. Any info would be much appreciated.
