[QUOTE="Blackhawk, post: 2001178, member: 105459"] [I]The Redding body dies when used in conjunction with the competition Shell holder set (caliber specific will bump the shoulder back just enough to allow the bolt to easily close on your sized round. Let me expand. Assuming that you have Fl resized your brass and trimmed to length if you go to the Redding competition shell holder page in the Redding Catalog it explains how to set up your body die to achieve the correct bump. If you have not read it very simply start with your shell holder marked +.10" and set your body die to make firm contact with the shell holder. ( Note if you have a cam over press allow it to do so.) 1) Now take this brass shell case and place it in your rifles chamber. 2) Try to close the bolt and lock it, however, do not attempt to force your bolt closed 3) Does your bolt close easily or is their resistance. 4) If your bolt will not close easily replace the + .010" shell holder with the + .008"shell holder and use a new piece of Fl resized brass repeat the process. I myself have found that I obtain an easy bolt closing using the + .004" competition shell holder and the .300 Winchester Magnum body die, however, your results may vary. Mind you that you must perform this set up for every rifle that you own in this caliber as chambers will vary slightly. With that said continue on until you find the Competition Shell holder that will allow your bolt to close smoothly and easily. 5) Write this shell holder number down and place it with your reloading notes. 6) You have now bumped your shoulder back enough and no further adjustments need be made. 7) Do not use a case length gauge as your chamber may vary slightly from Sammi spec however it may still be in tolerance. If the case fits into your chamber and the bolt closes call it good! Two Questions still remain : A) Why did you place a new body die in a wet tumbler? This die is metal and will rust if not thoroughly dried and something like Hornady One Shot die cleaner and case lube should have been used to clean and lightly lube your body die. I for one would never clean a die in a wet tumbler unless it was an ultrasonic type. Is this what you were calling a wet tumbler? B) How are you determining your COAL shoulder bump dimension.? Unless you are using an optical comparator, or say something along the lines of a Hornady or stony point type attachment that fits onto your digital calipers or something similar I don't know how you would actually measure your bullets shoulder bump. Or were you referring to the C.O.A.L.[/I] [/QUOTE]
