    OK, I was out with my new el-cheapo hunting semi-auto that I won at a Pheasants Forever banquet, but have kind of taken a liking to since even with one shell in the chamber and 4 in the magazine its lighter than my over/under that I have been hunting with for years.

    Anyway, I was out at the range function checking with my pheasant loads. The gun had been failing to load one into the chamber after 2 shots. This is a non-name-brand gas operated semi auto. They suggested I TAKE OUT the o-ring! Go figure. Lo, and behold! it actually worked.

    Anyway, I told you that story to tell you this one.

    Just for kicks, I went and retrieved a couple of the wads, and saw an odd thing.

    On both of the wads I found, I observed what looked like an extrusion of two little "nibs" right at the end of the gas seal cup.

    I wondered if maybe when I was loading these shells, the wad caught on the crimp at the wad station, but when I opened one of my unshot reloads, the wad looked fine.

    I kind of scratched my head for a moment, then it dawned on me.

    This has to be as the wad is traveling down the barrel, when it gets to the gas ports in the barrel, it must be so hot and the wad softens so much that part of the wad plastic is being pushed into the gas ports on the way by.

    Its all I can think of.

    Anybody seen this before?

    If there are two gas ports in the barrel and the spacing is the same, then that's it. As long as the nibs stay attached to the wad you should be okay. HMB

    Martin,

    These are WAA12F114's wads.

    The load is:

    Remington hull

    Win209 Primer

    30 grains of Hodgdon Longshot

    WAA12F114 Wad

    1-1/4 ounces of shot

    BTW, I talked to Kevin Lewis of Downrange about this. He's seen this before.

    He thinks it may be due to poor machining when they drilled the gas ports and didn't go back into the barrel and clean up any burrs.

    Given that it is a cheap gun made in Turkey, that sounds plausible.

    Some of the Longshot loads would melt any plastic.
