[QUOTE="Brent, post: 26273, member: 99"] JustC, Are your cases from the same lot? One thing I see you can do to eliminate the case capacity as the cause is to trickle all the charges and use cases that shot into the same hole while setting the cases that produced fliers aside, you may have to shoot them again if you haven't already set aside the flier cases though. If the "good" cases produce fliers in the same fashion and regularity after this, you will be certain case capacity differences have nothing to do with it. If the "good" cases produce nice consistant groups you can look the culls over to find the source of irregularity that is causing the fliers, measure water capacity, neck thickness variations between cases and around the neck on the same case, RO etc, etc. Bullets: Try another bullet like the A-Max to see if it produces the same fliers. A good comparetor to compare ogive length and weighing them also might be necessary if it leads to the bullet being the issue. Turning a thou or so off the necks to clean them up would leave you with a bit less neck tension which is all you should need for work at the bench or if you're single feeding them. I'd only waste the time to do this on new cases from the same lot if it came down to being the cause though. [/QUOTE]
