My Czechpoint Sporter (VZ-58) was bought New In Box in 2019, has used about 3,100 rds. A piece of every used ammo box is kept in a plastic baggy, and they periodically are counted.
Zero issue, so far, with this well-engineered rifle.
I often shoot my Maadi AKM mostly to avoid Ageing the VZ too prematurely-because I stored so much of the ammo over the years.
