The 22-250 likes the 52gr SMK as well if the Swift doesnt like the bergers. I'm running 34.7gr of IMR-4064 in the 22-250. She will drive tacks with either bullet.I've got 2LB of 3031 and 2lb of H-380 I'm saving for a 220 Swift 14 twist that's coming next week, be using the same bullets, hope they work.
