i have a cooey 600 bought last december. this afternoon i went to shoot a few ammo from a new box of remington golden bullet. on 20 round, i got 1 misfire and 2 round get stuck at the exit of the feeding tube. i was forced to disassemble the rifle 2 time to remove it. it's the first i shoot this model of ammo. is it common or just my rifle that don't like them.
