For gosh sake, take the .223 barrel. You'll extend your effective range quite a bit and be able to use 55gr. bullets in the wind. The polycarbonate tipped bullets vaporize picket pins and prairie dogs at extreme velocity. I use a .221 Fireball, .223Remington, .225Winchester, and a 6BR. If the town isn't spooked, we'll go in using semi-auto .22s with red dots for fast shooting. Just watch out for the rattlers! Have fun watching the predators come in for a free lunch, too. :lol:
