I awoke from a deep sleep, and thought to myself, "I think I put down .565-2 instead os 562-5." Thanks for the correction! I've got a back-bored Winchester SXP LongBeard and shoot a Carlson's .580 w/ the Lil Hammer, and per Ronny's observation and my own patterning, the Primo's .570 throws a great pattern w/ a phenomenal 10", but it's too tight for me for hunting. The more you shoot and pattern various loads and develop confidence in your gun, shells, shooting abilities and range estimation the tighter the choke which you can utilize which is true for, not only turkey hunting, but wingshooting as well. There is no substitution for shooting and practicing w/ your hunting gun of choice.
