my 2 cents: "Rem Mod 7 stainless, PacNor sporter barrel in 250AI, MPI liteweight stock (under 1 lb). Leupold 3x9 compact...hard to beat in my book. Weighs under six pounds and a dream to carry and shoot. I wouldn't shy away from the Ackley either. Mine shoots factory and handloads tighter than I can and it can be loaded pretty stout if one wishes to do so.

That 250 Remington Classic should be a contender too. A new stock if you like and you should have a real sweet varmint shooter.
Good luck.
