The Swift AI is a real monster and mitigates brass flow into the neck. The Swift brass is ultra-strong, few realize this. The brass flow in the std swifts I have had drove me crazy, not to mention the case trimming.
IMR 4064 is the standard powder for the Swift with 50-55g bullets but you will get MUCH more barrel life using AA2700, which is one of the coolest burning powders made with Rem 9 1/2 primers. In my rifles with 26" barrels, the accuracy node with 50g bullets with AA2700 is at 4000 fps, shooting 1/4" groups, and 3900 with the 55g Noslers, touch the lands with the bullets, barely.
The Swift AI is approaching the realm of the 22-243 AI in terms of velocity.
If you go down the Swift road, realize there is a world of difference between Norma brass and Winchester brass.
Of late, I went a 22-243 AI, shooting the 60g at 4000 fps out of a 23" retired Hart 22 ppc barrel, shooting single bullet hole size groups. Then had a Wilson barrel chambered to shoot the 60s, finished at 26", yet to fire that barrel.
I have had a number of 22/250 AI's, and there is no downside other than fire-forming brass. There is no downside in accuracy or speed in the 22/250 AI, which is slightly faster than the standard 220 Swift.
Back in the late 70s/80s, there was a jackrabbit population explosion. I shot the barrels out of two Ruger varmint in Swift, and two Savage 112 J Single shots. While being extremely accurate, it seems like I had to full-length size every firing or every other firing, and case length growth is nothing short of unbelievable. Brass flow into the neck caused accuracy issues when you are speaking of getting 5+ firings on Winchester cases. As soon as I purchased a Tube Micrometer and started measuring case neck thickness and monitoring brass flow, I wanted to get out of the entire 220 Swift operation as to avoid Inside neck reaming or Neck Turning. Late 70's/early 80s, quality neck turning equipment did not exist like today.
I do not own anything creed, but the 22 Creed is a logical choice due to quality Lapua brass, and it is a duplication of the 22/250 AI in case capacity.
If you want a real monster, the 22/6 Rem AI pushes the 80g bullets into bug holes with Retumbo, 215s at 3650 and NEVER use a full length sizer with 3800 being top end.
