I've shot so many dogs, the only way I can justify it is tellin' folks I'm a militant vegetable rights activist!
My buddies and I have tryed everything, including about a dozen wildcats, and I still shoot more dogs a year with a heavy 223 than anything else. They take a lot longer than a 22-250 to heat up, and in really good dog towns, that is your limiting factor. Regardless of what caliber you settle on, I
strongly reccommend a stainless barrel. Put a matte black barrel in the sun for a bit, and you'll get so many heat waves off the barrel you can't see diddley through the scope.
:banghead:
Speaking of scopes, here's another tidbit I had to learn the hard way. You
don't need top end optics for dogs. My dog guns are sporting optics from 4-16 to 10-40, but most are Simmons or Tasco. Prairie dogs, the
genteel little critters they are, like to sleep in. They don't get active for the day 'till it warms up, so the light gathering and transmission edge is not worth the $. Spend that money on
another rifle to shoot while that one cools off!
Good luck with your dogging. You'll
love it! Be
careful though... you can become a little obsessed!
