they are just fine.
My Nova have shot about 2000 standard hunting ammo (32-40 g)
a few hundred slugs and supermag hunting loads. And it has been in close contact with sand, saltwater, rocks, snow etc.. And it is as good as new (exept scratches). But the chokes (especially the super full extended choke) are worn out. Have only had one problem with it and that was a "federal turkey mag." (12/76 57g)
who had delayed ignition, it then fiered from a unlocked bolt (not good). but it is the cartridge and not the gun who is to blame for this.
