[QUOTE="Gene, post: 618106, member: 7402"] Most die manufacturers instructions say to turn the sizer die down until it contacts the shell holder, and you are good to go. Sometimes, this will properly full length size your brass. The problem arises when it pushes the shoulder back too far; thus increasing headspace, allowing more space for the shell to move forward then back, on ignition. Start with the sizer die turned up about two turns above the shell holder. Size, try the empty unprimed case in the rifle. If the bolt is difficult to put down, turn the die about 1/8th turn and try again. Keep doing this until you can feel the bolt go down easily about half way, then with just very slight resistance (thus the shoulder is just touching in the chamber) until the shell is fully chambered. At that point, lock down your die and you can F/L size forever. To neck size, keep the die at the same setting, and get a set of Skip Otto's shims from Sinclair, Put one or two of these under the die, and presto. . . .now you are sizing just the neck. Remove the shims, and you are ready to F/L size again. [/QUOTE]
