Coberhl

Just bought a sbe3 left handed, shot 2 boxes of shells at sporting clays, went duck hunting this morning and the gun fires the first shell but will not eject the shell. I noticed on the bottom of the gun the shell flapper sticks when you push it up. Touch the bolt and it drops back down, my dealer says shoot heavy loads but I’m shooting 3 inch hevi shot and 3-1/3 hevi shot and won’t get past the first shell. I did try other manufacturers this morning. Think I’m going to have to send it back.
