[QUOTE="fguffey, post: 1868210, member: 113511"] The case body diameter of shoulder/ case body juncture for the 308 is .453" the 30/06 chamber has less less taper than the 308W chamber meaning when the 308 W is chambered in the 30/06 chamber there is an interference fit at the shoulder/case body juncture by .014"+ again meaning the case of the 308 has to be crushed starting at the case body/shoulder juncture. I smith called to ask about his fired cases. When he ejected his 30/006 cases he found there was a ring around the case body about 1.559" from the case head. So I asked him if he was not happy with his 308W chamber? He wanted to know what that had to do with the problem. I explained to him the 30/06 chamber reamer will not clean up a 308W chamber. There are options F. Guffey Short chamber is one thing a short case in a long chamber is something else. Again, I have fired 8mm57 rounds in my 8mm/06 chambers, I know head space blah blah blah, The difference between the 8mm57 case from the shoulder to the case head and the 8mm/06 case from the shoulder to the case head is .127".
