I am already using a Forster FL sizing die and would like to have another one custom honed. Granted I don't have a ton of reloading experience but it just feels like the stock die is working my brass way more then it needs. I measured a loaded case and got .337 around the neck. In theory given all I have read I should be able to subtract .002 from that number and have a die opened up to .335 as a starting point. Guess my real question is about the instructions on Forster's website for this procedure. It says to measure the inside diameter of a fired case and go from there when requesting the amount of material to be removed. Can anyone point me in the right direction for having a custom FL sizing die from Forster made?
