I am 6'2'' and 330 lbs. and had the same problem, not enough drop and cheek slap. I fixed the drop porblem with a Morgan Butt plate. It fits on the end of the stock, replaces the recoil pad and allows you to put the recoil bad lower relative to the stock, thereby adding more drop at the heel. This gets the entire gun higher and straightens out your head. This also reduces the angle or slope of the top of the stock, almost makes it a parallel stock. With a parallel stock, as the recoils straight back, the stock sort of slides along your cheek. With a sloping stock, higher in the front than the back, as it comes back it the rise hits you harder in the cheek. In my case the recoil pad toe was contacting my chest first instead of the entire length. This causes even more cheek slap as the gun wants to rotate up instead of merely back. After I relieved, sanded, the toe end, the cheep slap is mostly gone.
