I am going to get the Vernier's out later and check, I do not have the deep 0 to 1" deep Mics so will have to guess on the tenths. I figure those wild shells what were chambered at least 40 times last season. Since I drop in the shell only the extractors really touch the casing so it must be head compression that should be easy to measure. I replace the shell every five times out now.
not loading from the magazine could be the issue. If the extractor doesn't pop over the rim you will jam your case mount into the Lands, potentially changing the neck tension/ crimp pressure
