Perfect for me would be a fast twist .223 as light as possible with a 20" barrel.

That said, I would dearly love for Ruger to come out with a rifle in the new .17 Hornet that is set up like their 77/.357 Bolt action.

5 1/2 pounds, 18.5" barrel, 6 in the magazine. Perfect for calling. Big enough for coyotes, but won't destroy a fox or bobcat.

It's all in the reflexes.
