I have used 6mm Rem, .270 Win and .264 Win Mag most bagged with handloads. But when I took my Son hunting I told him if he bagged one that measured 15 inches I would buy him a Rifle well he did and I bought him a new Remington 700 CDL. 25-06 Rem.
Winchester envisioned the .264 Win Mag as the Ultimate Deer & Antelope round and it has performed well in this roll. In truth all four have performed very well on Antelope.
