luke, go and get a CVA Optima Elite. You can get that in blackpowder and an 06 or 270. 2 barrels for the price of 1.You can get these if you shop around for $475-$600. Go to Buds Gun shop on line and take a look.
And after you save up you can get the shotgun barrel to go with it to go turkey hunting.
They are a bit cheaper than Thompson's and shoot just as good.
