well... let us say that for all the supershorts, the 243 really picks up a lot of steam over it's normal counterpart. And someday, we long gun idiots, either very old, or dead , and the new breed behind us, will have learned that these are far superior in design for powder burning and for bbl life.
That being said, this would be an excellent varmint , up to mule deer round. the latter two , i would keep the shots to 250 or less, and or varmints? I would take some across the canyon shots with it.
