Always wanted to do a Swift on a single shot action. If I do a bolt action it will be the Creedmoor on a short action, I have a PT&G 3.2" mag box should I need it. The standard action will get you up to 80 grain bullets with out too much intrusion into the powder area. The 220 AI would appeal also and I would load down like a 22 Howell to standard Swift velocity to improve brass and barrel life and less trimming.
