[QUOTE="bigedp51, post: 1567298, member: 28965"] Below is a bad case of runout in a factory chamber and the case neck was not touching the chamber. And a custom rifle with a tight neck chamber would have far less neck clearance. [img]https://i.imgur.com/uV3Munp.jpg[/img] Bottom line, bushing dies work best in custom tight neck chambers where the bushing does not reduce the neck diameter that much. And in a factory chamber neck turning allows the neck to expand more when fired. And the Redding bushing FAQ tells you that reducing the neck diameter .004 or more can induce neck runout. And a full length Forster die with a honed neck would be a better choice. [MEDIA=youtube]ac3iDJxDgxk[/MEDIA] [/QUOTE]
