SKS or AK47

Why is corrosive primer bad? You all clean your gear after you shoot? Is it just cheaper or is it not cheaper but more of a prefference? I suppose Id choose non corrosive over corrosive if I had a choice but does the cost saving not warrant the labor?
I have bad experiences with corrosive ammo. You think you have it all cleaned...but you didn’t get it all.

Not worth the risk of damaging the weapon. Just skip the corrosive stuff and never have to worry about it. The cost difference is minimal.
