I am trying to figure what cailber would be the best for what I am looking for. I want to be able to shoot 55 grain bullets at 3800fps or faster. I had a 220 Swift that I absolutly loved. It would push 55 grain Noslers at 3825fps. So what would y'all reccommend? 220 Swift...22-250AI...243...6mm something...ect...ect..???
