Trouble bumping shoulder - bad reamer?

[bigngreen]

Several die makers will make you what ever die you want, it's not there responsibility to make and stock dies for stuff that is chambered or head spaced tight or loose. The dies you get over the counter are generic, if you have special considerations give them a call and send them some dummy rounds, problem solved

yep, the situation your in goes like this;

your smith chambered your rifle with a tight headspace clearance for that cartridge, which is a good thing because you dont work your brass as much between firing and sizing.

your die was cut on the deep side of the specd dimention for that cartridge and would most likely work if you had a sloppy chamber.

Die makers should take notice of this, as many of us have tight chambers and face this problem, myself included. There is no reason we should be forced to grind the end of the die down to be able to bump. There is ample clearance to work with in this area between the case head and body of the case above the rim of about 150thou! - well within the limits of all headspacing possibilities. I wish they would take notice and stop selling dies like this...

Not sure what guns you are shooting but the difference between the recess in the bolt face and the shell holders is about .01". Thats the ammount of play you have before the webbing on the case will start to grow enough to cause extraction and or loading problems. Yes you can always polish the chamber a bit more but who wants to do that if you do have the stuff to do it in your garage yourself.
