[QUOTE="woods, post: 260406, member: 6042"] I have not done any tests with case necks prepped in different ways. Normally I use steel wool wrapped around a 22 caliber brush so that it is a very tight fit in the case neck [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSCN0719.jpg[/IMG] This removes everything including all burrs and scratches. I also dip the neck down into mica afterwards and wipe it off the outside, leaving full coverage on the inside. This all helps get consistant seating depth for me. If I outside turn or inside neck ream, the inside is always all scarred up [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSCN0721.jpg[/IMG] and the steel wool will greatly improve the inside neck surface [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSCN0720.jpg[/IMG] It always seemed to me that the bullet would have to be moved to the lands and even partially down the bore before the expanding gases would occupy the case neck and expand the brass to the chamber neck. If that were so then varying bullet release would make a slight difference in the pressure progression. Anyway it is worth the effort to me to get 100% consistant bullet seating depth which I do know affects accuracy. [/QUOTE]
