I shoot a 6.5 06 IA it is awsome. Dropped an Elk at 600yds plus many deer at over 500 yds. My goat took one step. 3185 ft 25" barrel. 500yds my group is 4.5
I shoot a 6.5 O6 IA
257IA built by PO
280 IA and a 30-338 25 shoulder angle
I like the 6.5 the best have killed Elk, a Goat, and Mule Deer it accurate :pgun)
