Would like a rifle and scope, with flat trajectory, enough knock down for blacktail, whitetail, and Muleys, with a scope that adjusts and is capable of shots at less than 100 yards and out to 350 yards if necessary. Is there a set-up for tis? .270? 7mm? I don't mind a little kick, but i don't want something that is uncomfortable to shoot and practice with. Looking for quality. Used is okay as long as in great shape. Any offers?
