Great responses on camoing your gun fellas!!Once again constricting movement is the priority here!Now this choke thing is a pet peeve of mine!Patterning your gun is the priority here!!Guys spend a fortune year in in year out on patterning there firearms which is a great thing in increasing your pattern density down range!But imho turkey hunting is a close range sport and I've killed literally dozens of birds with block stock and barrel firearms,including the one I shoot now.Obviously patterning your gun is where it starts and if theres a problem there than an adjustment HAS to be made!But in many cases it is not neccessarily a NECESSITY as is being engraved on all modern day turkey hunters minds!Obviously there isn't anything wrong with a guys desire to increase his pattern percentage but the question is,is he doing it for exactly that or to increase his range?To me 40 yards is max not because I cant kill a bird further but simply because the high of the sport is foolin them in close,once again IMHO!!I agree with MTT here good sites are an asset especially in helping with low light conditions and for the individual that has a sight problem but to say your gun has to be fitted with an after market choke and that it is an absolute neccessity depends on if there is a problem with your current set-up AND what YOU individually want out of the sport!!Theres no question modern day gun smiths coupled with the loads we have now, can hook you up with a set-up that will thump gobblers at long downrange ranges but to me this advocates puttin the call down and the stalking boots on!!Pattern your gun it will tell you what you need to know!!
