I'm with Frizzelr on this one...I like the 243 in a varmint cartridge and personally have seen a 180 class Mulie harvested in a Alfalfa field in Colorado and it was a one shot kill...the Lady was using a Remington varmin rifle...I like the Ruger varmint rifle better but the trigger has to be replaced or reworked but so does the Remingtons's.
