The rifle is an M1A.
I ran into a problem today I dont understand. When I sized the 30-06 brass down to .308, I checked the headspace on each newly sized round one at a time with the Hornady headspace gauge. (the one that goes on the calipers).
My Rifle headspaces at 1.631.
I set the headspace of my rounds at 1.626
When I drop the cases into the Lyman headspace gauge, (the barrel shaped one that mimics the chamber), The case head sticks out too far. Actually quite a bit.
I took the round, and checked the headspace on the Hornady tool again, and it checked fine at 1.626.
I took the round and slowly chambered it into the rifle. I still had the extractor in the bolt, so I bumped the charging handle to catch the round, then pulled it out a bit, and slowly let the bolt ride forward, and it closed with only a little "bump" from my hand.
I dont get it.
Are these rounds safe?
