[QUOTE="MNbogboy, post: 1688393, member: 18849"] Sorry Edd I don't have that print but after study of some published prints it is clear that the creedmoor chamber may not clean up without setback. Sorry to the OP for misinformation. Creedmoor reamer print shows .4630 to .4634 at shoulder with taper at only about .007 per inch. The 100 thou deeper won't make up the difference of the A.I. at .4600 to .4604. Good catch Edd...better now than his smith catching it or worse yet stuck case after first shot. If anyone wants I can do the math for the amount of setback but my guess would be a min of 1/2 inch. [/QUOTE]
