[QUOTE="Reloader, post: 133437, member: 2555"] [ QUOTE ] XP, I do believe that the Bersin Tool fixes bullet "cant" not run out. Run out can only be fixed by ensuring that the bore of neck and the case body diameter are on the same axis. Ian. [/ QUOTE ] I disagree to some extent. Run out can be brought on by other means even if your brass is "perfect". Loading techniques, seating dies, etc. can all contribute to excessive run-out. Also, I've never heard anyone refer to a misaligned bullet as being canted but, not having run-out. Run-out simply means the central axis of the bullet is misaligned w/ the central axis of the case and creating a loaded round that is not concentric. These off centered rounds can be straightened by means other than a Bersin tool if you don't desire to go that route. A simple hole of the proper size drilled into a hardwood block works fine. A slight amount of pressure on the case while the bullet is inserted into this hole can straighten the round to an acceptable level. Notice I said slight pressure, if you are too rough w/ them you can effect neck tension greatly. Good Luck Reloader [/QUOTE]
