[QUOTE="elkaholic, post: 317913, member: 13833"] Don't want to throw a wringer in, but I've had a 6.5-06 A.I. and currently have a 6.5 Sherman based on a .270 case. One thing that you want to be aware of is the 25 and 30-06 measure 2.494" The .270 and .280 measure 2.540". Someone mentioned that you can just fire form the '06 case and have at it, which is true. The problem is, when you fire form this case, it will shrink in length by .015-020", then you have something like 2.475 or so. My 6.5 Sherman reamer measures 2.525" to accomodate the shrinkage from 2.540 in the .270 case so you don't end up with a short neck as I previously mentioned. Also, many of the factory cases are shorter than advertised in the beginning, SO YOU CAN END UP EVEN WORSE OFF. My case has less body taper and more body length than the A.I. and still has a good neck because of the greater .270 length. (I.E. WSM CASE CAPACITY IN AN '06 SIZED CASE) I get 3200'+ in a 26" barrel which is about 125' more than my ackley would do.
