    The factory setting seems a little wound too tight.  The pellets slam as they index. I tried moving the spring to the next hole to loosen tension, and it was too lacked.  The last shot would sometimes not index, as the drum stalled out due to poor pressure.

    So I compromised by drilling a hole in between the two factory offerings and the result is just right.

    My Hole is at 7 o’clock!

    I had to put a post-it note around the bit to get the chuck to grab……

    and the size, .046 inches.




    Did consider this when I modded my magazine to smooth the cocking but managed to get it right setting the centre screw correctly, plus some silicone lube.  

    Mine would do as you said, would be like a total jam hitting between the pellet guides.
