My smith and I are lookin at the possibility of a 220 swift that will shoot 90 grain vld's. I personally think a 7.5 or 8 twist is best at about 24". Can anyone tell me anything about this setup or if you know of anyone who's tried? I'm lookin for maximum distance out of a tiny cartridge. I have no interest in factory anything and only care about using the 90 berger for the bc and sd. It's a light little round that I think could do major damage with the right setup. Please feel free to show me your setup if you have one. I'm lookin at using an AAC Action, krieger barrel cut to magnum contour and fluted, a Manners SL, badger bottom, and aics. I want to make it as light as possible since it don't kick too much.
