So I am prepping to start reloading for 6mm arc, hopefully this week if all goes well.
I just got in my LE wilson headspace gauges today and decided to check the headspace on my bass. However the brass did not want to go into the gauge. I ended up putting the brass in, and dropping it, brass down, onto my table a few times which caused the brass to seat. had to use and allen wrench down the inside with a few taps to get it back out.
as near as I can tell its binding just below the shoulder.
I measured 7 cases and as best I can tell the fired bras is 0.017 over max headspace length.
Factory brass drops in the die and it fits like a glove. almost no wiggle room. In my past experience the gauges were a bit loose on the body to allow for once fired brass to drop in easily. but with the way factory ammo fits i am almost wondering if the die is just a bit on the snug side.
Or based on the headspace measurements, it may be that my chamber is a bit overly generout.
and before you ask, I did buy and use headspace gauges while assembling, it closed on the go, and did not close on the no-go.
Also begs the question. If it want to preserve maximum brass life, should I just bump the shoulder a few thousandths? or should I take it to max headspace per the gauge to ensure reliable feeding in my semi auto platform? Iv honestly never really though about how much brass grows. is 0.17 a lot or a little relatively speaking? I know if you bumping the shoulder 0.003 I would assume that's the grown vs neck sizing fire formed brass....
I did contact LE wilson. Waiting to hear back. Just figured I'd pick your brains while I was waiting.
