“I'm assuming the 1/8" holes are too large and these are certainly not "once fired." “

Not sure about my quote of a quote but... 1/8” or .125”, depends on how the flash hole got to be .125”, I have almost given up on measure before and again after, does not seem reloaders/shooters are interested in where they started, most fire first then measure. For that reason if you do not know the diameter of the flash hole before firing little information can be gained by measuring after firing. BUT! if the flash hole is ..070” in a new case before firing and .125” after firing you will understand why I say the beginning signs of excessive pressure starts from the inside of the case with the flash hole, primer pocket and crushed case head. Again, WHO MEASURES?

I have shell holders that fit, my favorite shell holders are the ones that fit only where they touch, loose shell holders have versatility.

Shell holders that fit cause reloaders to ask, ‘What is wrong with this 40 year old shell holder?’
