Cons: Short case life. The tapered brass on the swift case tends to stretch with firing especially if you run it hot. If you load it with 50 and 55 grainers you don't gain much over the 22-250.
Pros: Shoots very flat, and if loaded with 55 grain bullets carries good energy for those 350 yard plus shots.
Bottom line: New cartridges such as the 204 ruger give the same performance and are much easier to shoot with the same ballistics.
