[QUOTE="antelopedundee, post: 2071020, member: 107384"] I would suggest that you invest in a decent caliper and one of these Sinclair bullet comparators. Before you do anything you should sort through a box of bullets and find 10 or so that have the same bullet length and the same distance from base to ogive as determined with the Sinclair comparator. Next you should turn [or find a friend to do it for you] some case necks to uniform wall thickness. Your case necks should be just tight enough to hold a bullet. Seat a bullet that's longer than COAL plus some extra. Chamber it in your rifle until you can feel it touch the lands. Save this as a reference dummy, assuming that your chamber is relatively new. Turn the seater stem in until you reach the amount of "off the lands" distance [say 0.020 inches] and seat some bullets using cases sized to however much neck tension that you want. Your 10 sorted bullets should all measure the same COAL with the Sinclair comparator. Maybe randomly pick 10 bullets out of the 90 left in the box and see how COAL measures. Many times there are differences in bullets from the same box. You will not be able to accomplish much of this with just a standard set of dies. You will need either the neck size bushing approach or a set of expander mandrels which you use to set neck diameter AFTER you FL size your cases WITHOUT the expander stem assembly in there. GOOD LUCK. [IMG]https://i.imgur.com/Pz74K8y.jpg[/IMG] [/QUOTE]
