For some reason I have a bug to pick up a rimfire single shot handgun for general plinking/varmint hunting. Not stuck on rimfire, but really like the 17 HMR but open to 223.
TCA's Encore or Contender line is probably the one most folks are familiar with, along with the Weatherby CFP, Ruger Charger, Savage Striker and the more obscure MOA Guns, Brown 97D and Freedom Arms 2008 Single Shot.
I have a Brown 97D rifle in 6.5 BRM and like the falling block design over the break action on the TCA but not a major issue. Affordable caliber swap on the TCA is an advantage, compared to MOA guns and FA.
Anyone have any experience behind one or more of these?
