I have always used Redding and Wilson dies through the years for reloading. I have never had custom dies made for a rifle that i had built and i am thinking of having it done. In the past i have necked sized till the brass needed sized and have used the Wilson bullet seater and the Redding micrometer die also. The way i am going to reload for these 2 is to seat bullets with a Wilson micrometer and i want to have a die for a press that full length sizes, bumps the shoulder and neck size in 1 pass. I know that Redding sells these dies and Harrels does not due the 2 calibers i am doing. Neil and Warner make dies their that i could have done. So my question is could i have my smith ream me out a chamber off the extra piece of barrel left over to send out to have this die made from? Would it be better than sending fired brass? Would it even work? I do not have a problem sending out fired brass to have this die made but if it has to be a piece of brass that has been fired 2 or 3 times from my chamber to get a die made then i am going to have to buy a die to size my neck to get a 2nd or 3rd firing from the case. I would like to know what you fellows due when you have dies made for your rifle and how you go about it. Do most of you guys use someone that also makes dies to when you have a barrel chambered.
