I now have about 100 rounds through my 10 FCP-K .308 and today I was shooting some military match M852 7.62 ammo from 1993.
Any way I noticed on a few of the rounds of this ammo the bolt seemed a bit snug during lock up of the bolt. I did get all the rounds chambered but like I said some were a bit snug during lock up. Seems the headspacing was a bit tight.
After returning home to clean my rifle I noticed that some of the black coating on the back of the bolt locking lugs is starting to wear off.
I do grease the lug faces before shooting to make sure there is no galling or binding.
Is the black wearing on the lugs normal ?
What other type of wear should I notice on the bolt and lugs during normal use?
Oh and BTW this ammo shot great I was consistently getting .5 moa groups.
