[QUOTE="MNbogboy, post: 1689404, member: 18849"] Here is a copy of my pm to IanCo [LIST=1] [*]257 Bob Ackley is a fine choice for a short action. I have chambered & built 3 of these. Ballistically like a 25-06...had very good luck with 100 grain Nosler ballistic tips at about 3150 fps.. COAL running about 2.900 to 2.950 which fits in most short actions. [*]Have chambered three 6.5/257 Bob A.I.s. [*]COAL on some bullets like VLDs run a tad over 3" (ie; 3.010 etc). May not work in a short action. I have used long actions on both calibers. The 6.5 Bob A.I will shoot 120s at over 3000, 130s 2950ish and 140s at 2850 to 2875. Both calibers are perfect for deer & antelope. Mine are all sporter contour but still shoot under 1 moa on the 600 yard range. It is good to see others taking interest in the Ackley Bobs. Randy [*]He responded that he wanted to shoot the new heavies and would do more research. [/LIST] My final response was to the effect that they might end up long. [/QUOTE]
