[QUOTE="budlight, post: 1023214, member: 2939"] I came across this on the Redding site. I only use RCBS and Lee Question: My Type "S" Die will not size the neck of my cases and/or my bullets fall into my case with no neck tension. Answer: Type "S" Dies require a Bushing to size the neck of the case. Bushings are not included with the Die and are available for purchase separately. Question: What Bushing do I need for my Type "S" Die? Answer: There are two methods for choosing the correct bushing. They are as follows: 1) Measure the neck diameter of a LOADED round or a "dummy" round that you've produced with the brass & bullets you plan to use. Now, simply subtract .002 from the diameter you measure to select the correct bushing size. a. The use of a Micrometer is advised for these measurements but a Dial Caliper may be used if a Micrometer is not available. b. Measuring a sample (several) loaded rounds and using the average is advisable. Example: My loaded rounds measure .300 at the neck. .300 - .002 = .298 Thus, a .298 Bushing would be appropriate.
