I have a Beretta 686 onyx and have been having misfiring on the bottom barrel. When you looking at the firing "pin" it seems more recessed than the upper pin. The pin will fire but often times not enough penetration on the primer cap (not sure if that is what it is called). The gun is relatively new with only 15 boxes being shot with it. Any advise would be helpful, tried cleaning but no change. thanks...

Once you take the buttstock off the receiver, it probably won't be necessary (or advisable) to remove anything else. Buy a gallon of kerosene and pour some into an old coffee can or similar can. Then just stand the receiver in the can full of kerosene for about an hour. Remove and let drip dry onto paper towels overnight. Then lube with oil or grease and reassemble. Breakfree CLP is an excellent "oil".
Be sure to use lubricant (I prefer grease) on the pivot points (trunions) inside the receiver and on the forend iron where it contacts the front edge of the receiver when reassembling the gun. Do this all the time, but especially when the gun is new. Periodically remove the old grease and replace with new grease (or oil if you prefer).

I would say that Mr Ben is probably right as to the cause of your problem, but I would try a couple of things first before sending the gun in.
First, apply a lightweight, penetrating type oil to the cocking rods and try to get the oil to work its way back into the enclosed part of the action and into any recesses or channels in the receiver. IOW, lubricate those rods well with an oil that will spread. Then, open and close the gun and dryfire it repeatedly to help spread the oil.
Second, try different types and brands of ammo.
If you still have the problem after doing both of the above, send it in to Coles or back to Beretta. Likely all it needs is a good cleaning and lubrication. Heck, you could probably take the buttstock off and do it yourself. Save yourself some money and learn something about your shotgun at the same time.
