I have a CZ American in 222 Rem. Over the 3 years of using this gun (bought new by me) the MAX COL (not headspace as I originally posted) has increased about .045 inches. I have no exact count of rounds, but less than 3000 for sure. Never loaded super hot. When I clean the bore , looking into the throat with strong reading glasses the throat looks practically pristine---no signs of erosion to the lands. 222's have a reputation of extended bore life, so this has puzzled me. Still shoots sub MOA, but used to do 3/8" regularly.
It occurred to me while cleaning it today, could the bolt lugs be wearing which would let the bolt face back. What do the bolt lugs look like to those of you that have experience and most of all to owners of CZ micro bore rifles? Looks to me like they could be wearing.
Thanks!
