If your primary use of the smoothie will be to shoot standing game, like deer, or turkey, then consider a rifle style gunstock. If your primary use of the smoothie will be to shoot birds, and small game, where you have to move the gun as you would a shotgun, Then get a shotgun style gunstock. The Tulles are nice guns. The fowlers are also nice. You won't be disappointed with the workmanship of TVM( Matt).
If they made them in LH, I would probably be owning and shooting a Tulle. But they don't, or didn't. I have a LH fowler. Where I live and hunt, small game and birds are the primary hunting game. We have both whitetail deer hunting, as well as turkey hunting, but the seasons are limited in the days you can spend afield, compared to hunting various species of birds, squirrels, rabbits, etc.
If you are a rifle shooter, and Not trained to shoot a shotgun, then you need to get training to shoot a shotgun well. The footwork, stance, how you point the target, how you use the sight,
and slap the trigger are totally different than what you do shooting a rifle.
Its easier as a shooting coach, IMHO, to train an experienced shotgun shooter to shoot rifles, than it is to teach an experienced rifle shooter to shoot a shotgun well. :hmm:
Likewise, if you have only fired a percussion rifle, its going to be a bit of a challenge for you to get used to shooting a flintlock. There IS a learning curve, and having an experienced flintlock shooter on hand to help you learn is a valuable asset. :hmm:
No one can decide FOR you which of these fine guns you should own. If I were RHed, I probably would own one of each! :haha:
