[QUOTE="woods, post: 318760, member: 6042"] Do-nuts are where the shoulder brass flows toward the neck and causes a ridge at the shoulder/neck junction. The easiest way to tell if you have one is to insert a bullet into the neck of a FIRED & UNSIZED case. If the bullet will not go past the shoulder/neck junction then you have a do-nut [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/3D-308-doughnut2.jpg[/IMG] Another way is to get a set of pin gauges [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1487.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1489.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v663/bwestfall/RELOADING/DSCN1493.jpg[/IMG] The only way to get rid of them is to inside neck ream. Since you are getting the Forster, they do make a reamer that will fit the outside neck turner. The reamers are .003" over caliber diameter so if you set your brass up for .003" neck clearance in your chamber, then when you once fire you will have .003" inside neck clearance and can insert a reamer into your outside neck turner. The way to tell the size of your neck in your custom chamber is to measure the OD of a FIRED/UNSIZED neck. You may have to allow for springback but it will be close. [/QUOTE]
