What Ruger-Redhawk said.....

Also, yes the .220 swift is basically the fastest varmint round alive. Not counting the rare wildcat loads.

Picture this. A .220 swift is a little .22 caliber bullet sitting on top of a 30-06 case. What power, speed and in some cases, mid flight desintigration!!!!

Go with the slower .22-250 instead of a .220 swift for varmints.
