Hi everyone, I admittedly am going this a little backwards. Well maybe, maybe not:
I am following Glen Zedikers book Top Grade Ammo in which he recommends.004 set back from fired cases for safety in semi autos. So I have unfired cases at 4.060 and fired cases at an average of 4.065 if I use his recommendation I would set the shoulders at 4.061. To me that makes sense.
I have 3questions:
One is it accurate to take the fired case readings from a different brand of case? I don't have any unfired cases as I shot them all up before reading about this so I used to other brands of new cases and they actually were the same at 4.060
Two: I have once fired resized cases of a 3rd brand that measure 4.063, which is obviously .002 more than the .004 recommended at .001. Now he did say .002 or .003 could be ok in a clean chamber which mine is. Do I need to resize these again to get that .004? I also resized before reading about this using the die makers recommended method which is why they came out that way.
Three: And if so do I need to trim again?
Thanks
