Re: Info on 220 swift AI, 22 243 , 22-6mm
I shoot the 220 weatherby rocket which was Roy's first wildcat. It is off the blown out 220 swift case and about the same as the 220 swift AI. My accuracy loads with a 52 grain match bullet hit around 4100 fps with 47 grains of IMR4350.
Predictions are difficult, especially when they involve the future
