[QUOTE="bigedp51, post: 1371097, member: 28965"] Redding competition shell holders will "NOT" push the case as far into the sizing die as a standard shell holder. There are 5 shell holders in the Redding set and the deck heights are .002 to .010 "LOWER" than a standard shell holder. The deck hight on a standard shell holder is .125 and the +.002 shell holder is .127, +.004 = .129, +.006 = .131, +.008 = 133, +.010 = .135 Bottom line the Redding shell holders give you "LESS" shoulder bump and still allows the die to make hard contact with the shell holder. This means the die is never touched or adjusted for shoulder bump and changing the shell holder controls the amount of bump in .002 increments. If the die does not push the shoulder back far enough, the simplest and cheapest thing to do is lap the top of the shell holder. And doing this will push the case further into the die giving you more shoulder bump. Just remember we live in a plus and minus manufacturing world and your problem shell holder deck hight may be more than .125 and causing the problem. [/QUOTE]
