A good turkey choke will tighten your shotgun load for that maximum one-shot performance. That single trigger pull you need to drop that turkey in range depends on it. If you're like me, part of the confidence factor in killing gobblers is proven time with a certain firearm, choke and load. You don't think too much about the matter after that. Clean your turkey gun, store it safely, maybe pattern it a little to get in the groove of things, then hunt the next time out.
