How about a Remmy M700 SPS Tactical in .223 with the factory 20" barrel that is already a 9" (1 turn in 9") ?? It can / will handle the 68's, 69's, and 75 grain bullets for longer distances. I have shot these bullets at the National Sniper matches from my Winnie M70 Coyote .223 sporting a medium profiled 9" twist barrel.
Shorter 20" barrel for your walking adventures, fat & stiff barrel for the gopher shoots!

Yeeeha... what not to like? Just gotta get used to that goofy feeling Hogue overmolded rubber coated stock. Actually, my buddy loves his .223 SPS Tactical AND the Hogue stock. He just adores that rubber feel!
Hope this helps!
