I bought a brand new Beretta 686 White Onyx 12 gauge Sporting five days ago. On that day I fired a box of my reloads ( Federal hulls,1oz. 8's, CB2100, 18.8 grains of Promo and 616 (209) Fiocchi primers) with no problems. Today I shot a box of my reloads (AA hulls, 1oz. 8's CB 1100 wads, 18.8 grains of Promo, 616 (209) Fiocchi primers. I experianced a problem in that I loaded two shells, fired one shell and pulled the trigger for the second barrel. It did not fire. I did not hear the pin fall. I was unable to to open the gun, move the barrel selector or place the safety on or off. I tapped the butt with my hand. Nothing! I pointed the barrel in a safe direction and slammed the butt on the ground. I then pointed the muzzle in a safe direction and pulled the trigger. The gun fired. The top leaver worked fine as did the barrel selector and safety. I went on to shoot the rest of the round with no further problems. My question is " Do you think it was my reload or a major problem with the gun?" Serious responces are requested. Thanks in advance. Jerry Felice
