I have 1 7x57 [A Remington 700 Classic] and two 6.5x55 Swedes [One is also a 700 Classic, the other a sporterized M96] I have shot all manner of game with both chamberings, and do not feel handicapped when packing either. These are both proven performers, and are capable of easily taking all cervids and other game animals in North America. [with some caution regarding the big bears] What can one say. I guess if push comes to shove, I will take the 7x57, but only because of the wide selection of 7mm Bullets out there and the heavier weights easily found [160. 175 Spitzers] Regards, Eagleye.
