RE: 4 vs 5 shot size
My Browning B-80 consistantly put 16-18 pellets into the head and neck of a turkey target with the 3 inch Federal Premuim 2oz #5 loading at 40 yards...With #4s it drops to 6-8 pellets...with 6s I have holes in the pattern...So I listened to my gun...And I have rolled 2 turkeys in the past 5 years at an honest 40 yards...I have killed 8-10 with this loading in the past 6 years, but these two hung up at 40...My hunting buddy killed a gobbler on the second day of our season last year at 53 steps with the Winchester Supreme loading, using #5 shot...Number 5s will do the job...
btw...My dad grew up in the Depression his dad had a country store, dad quit school in the 5th grade to hunt and help his dad make moonshine which was sold at the store....Dad killed hundreds of turkeys to sell with a single shot 12 gauge, 2 3/4 chamber and #6 lead shot...
