Short answer, "No." It is a momentum thing, IMO. If the slug were to decelerate, even a small amount, there would be a gas hammer behind it and a bulged barrel a distinct possibility. Total recoil is, of course, dependent on ejecta weight and velocity. Said momentum is translated to free velocity of the recoiling gun, depending on its weight. Said weight and velocity of the gun give recoil energy. "Felt recoil" may have to do with instantanious acceleration of the ejecta. That is, the shooter "feels" the rearward acceleration, or maximum acceleration, as opposed to the total recoil (that ought to start a debate!!!). Anyway, I dn't see how ejecta can "grab" the barrel and pull the gun forward.
