Thread: Full length sizing issue

If I wind the die down on to the shellholder, which I assume woudl give me maximum shoulder bump, I am getting no shoulder bump at all and in fact my cases are increasing in length from 1.6340 to 1.6350.
Can anyone tell me what is going on here? If I wind the die in any further it just starts pushing the ram down.

Looks to me as though your cases are short. First question do the cases chamber in your rifle? Some details on the cartridge, load and history of the cases would help narrow down the problem if there is one.
