I'll start by saying I'm a new reloader and sometimes make things more complex than needed...
I'm reloading for a 7mm rem mag. So belted case.
I have a redding competition shell holder set and hornady headyspace gauge and have set out to only bump the shoulder .002. I fire formed some hornady brass and figured out the right shellholder to get the .002 bump and thought I was golden.
That was until I measued the once fired brass compared to 2x fired brass using the headspace gauge. The 2x fired brass measured .002 longer than the 1x brass. Resizing both they bump .002 but the 2x fired brass is always longer by .002.
To complicate this further in my mind. I has some once fired in same gun FC brass that when I resize using same shell holder the shoulder does not move at all but ends up about the same measurement as the once fired resized hornady brass.
So is it ok/normal that the 2x fired headspace measures longer than 1x after both were resized? (Both bump .002, the 2x brass is longer from base of case to shoulder by .002)
Is it ok /normal that the FC brass shoulder did not move when resizing with same shell holder/die setup as my other brass?
I'm confused as hell.... Should I continue to use same she'll holder and size away and not worry about the difference as long as shoulder is bumped? Should I sell all my stuff before I blow my gun up?
I watched a video broz made on bumping the shoulder and it seemed like once you got the right shell holder you were good to go.
Please help...
