Cgturner,welcome aboard here...Loner gives good advice,the key is a tight consist pattern out to the 30 to 40 yard mark.This is generally achieved by matching your choke constriction(preferrably full or tighter)to the load your gun likes best.Brand of load and shot size can make a big difference in the consistency of your pattern so as Loner mentioned its up to you to find which one works best.We like patterns tight simply cause without a head-n neck shot your gobbler will leave you wounded![:'(]I'll add one thing here considering your new to the sport!I appreciate the fact you already understand this is a one shot sport if done correctly and what greatly attributes to that is having that gun up and ready when that gobbler gets in tight.If that bird see's you moving your gun into position for a shot because you waited to long to get that gun up than your faced with possibly a longer shot because he saw something he didn't like or worse yet a running shot.Stumps,trees,bushes,small rises in the terrain,and even the fan of the gobblers tail all can block his view of you as he approach's and instead of getting caught up in the moment take advantage of these opportunties and move that gun into position for an easy shot opportunity!No your range and give it to him and you'll be one happy turkey hunter...Good luck...Bob!!
