Which caliber is best???
I wanting to get an exellent Pronghorn/Deer rifle. My options are 6mm Rem, 243, 25-06, 257 Roberts. I hunt in the wide open spaces of Arizona so distance is a concideration. I want something that has a very flat trajectory and a lot of punch out to 200-300 yds. Is this possible? How is Ruger in any one of these calibers?
