It's so ridiculous it's sad to the point of funny.
In the unlikely event that a crowd of unknown hunters should wander over, play dumb, talk with your mouth full, drool, and entice them away from the area of the howitzer. If they comment about the "smell of rotten eggs" ( the sulfur form the 1/2 pound of black powder you just ignited ) tell them you ate a lot hard boiled eggs for breakfast, and you have gas.
Thats just great..[&:]
10. In the event that you "do" have unscheduled on-lookers while you are field dressing the deer, ( especially if a Game Warden happens by ) be ready to explain to him that you got very, very, excited and that you kept shooting your "12 gage shotgun" until the deer finally went down. Tell him you fired "at least as many times as you find holes in the deer". Take him over and show him all the empty cases which are strewn about. ( the ones you previously spread-out far away from the Mountain Howitzer I hope) Act very, very, excited and be very, very, convincing. ( your freedom may depend on your acting ability ) You may need to tell him that you had to reload, two or even three times, depending on the number of holes you find in the deer. ( the pattern of your individual mountain howitzer cannon will dictate the extent of your tale ) However, if you shot your deer at less than 100 yards, this may not work at all, and you will now be in big trouble. ( Hopefully the Judge will have a sense of humor when he exclaims to the Game Warden, .............. "You telling me he actually shot a Deer with a Mountain Howitzer Cannon?" )
