Rifle: Tikka Tac .233
Ammo: PMC Bronze .223
Dies: RCBS Full length .223 set
When I measure a fired case from this rifle, they are measuring in the 1.4480" area, which seemed short to me.
I started to set up the dies for this rifle, and ran out of adjustment before the die touches the shoulder. My press was camming over and the brass was growing to 1.4505" or more.
Before I did anything drastic like grinding the bottom of the die body off, I checked a few things.
I was using a RCBS Rock Chucker to set up. I moved the die over to my LNL AP to see if maybe a different press and shellplate would make a difference. Nope.
I got the rifle out and dropped the brass in. Chambers just fine, even at 1.45?"
Ok??
I measure a new PMC Bronze from the same box I was shooting. 1.4510 - 1.4530.
How is my fired brass shorter than factory ammo?
What should I set my resizing die to for length?
The only thing that I did that could possibly have an effect on length was run the fired brass through a Lee universal decapping die to knock the primers out, but that doesn't touch the shoulder.
Help?!
A little more info to add to the confusion:
Various ammo I have laying around
Factory Lake City 5.56: 1.4510
My reloads for an AR: 1.4560
All of this ammo chambers fine in the gun. How can my fired brass be so much shorter?
