You know, the notion of replacable chokes in varying degrees (IC, mod, full, x full, etc...) is fairly new. At one time not too long ago, MAYBE even in TiT's time, there was 2 choices...Choked or Not Choked. The closest thing to a full choke was a Long Tom Goose Gun with a barrel around 36 inches. MOST Choked guns were Modified at best a few made it towrds full and a few not quite to Modified, but they were choked. 2 3/4 inch was THE shell size for 12 gauge. That all said, them old time hunters ALMOST wiped out the wild turkey in this country with those scatter guns that MOST hunters would not even THINK about taking to the woods.
Point is...Do you NEED 3 1/2 inch shells??? No, they'll hurt YOU and the game more but NO you don't NEED them. Do you NEED treplacable Chokes??? NOPE again...But you DO NEED to learn to hunt them right. and what about all those gadgets and thingamabobs???? NAH....not really. Think about what our forefathers hunted with and how...You MIGHT be surprised at the answers you come up with.
