Unless you are doing this to experiment or just want a unique round to call you own and want to play with shaping brass etc

both the swift and the 22-250 are good rounds. the 22-250 a bit easier to find and maintain. If speed is your need, than the Swift would be the choice. If longevity of equipment than the 22-250. I have that in a lot of forms, including an UMAR and it has always served well
