First is the Charter new? What load on the ammo? 6 rounds that wouldnt fire? Any noise on these rounds? Is the primer dented? Seems alot of things going on. My guess-ammo. Try box of name brand jacketed bullet rounds. This only if NO safety issues exist.a freind of mine just bought a charter arms 38 spl offduty model he shot a box of ammo through it the first day out .out of that box of ammo there were about 6 rounds that wouldnt fire ,the cylinder wouldnt spin to lock in place .we found out the lead on the round was touching the beginning of the barrel .after looking the lead was not seated all the way.we blamed it on the ammo. day 2 totaly new box of ammo ,even a diff brand same thing again .when the cylinder spins the lead touches the barrel flang.any one else have this problem?
