RE: 00 or 000 buckshot?
I've killed a few truck loads of deer with buckshot, both 2 3/4 and 3 inch shells...
It doesn't matter, let the gun tell you...It's about like argueing over #5sor #4s for turkeys, either will kill as far as you should be shooting at them with a shotgun...Too many guys want to shoot at deerand turkeys past their effectiverange with a shotgun and that's not what they are designed for...
My 1100 prefers 2 3/4 Winchester #1s...My Browning prefers 3 inch Winchester 00s...Both kill out to 40 yards which is where I limit my shots to...
The 1100 gets to go when I'mgoing to the swamp and there is a 1 oz slug as the first shot...If I hear the dogs coming I can eject the slug and add another round of buckshot...The Browning goes as a backup to my .243 when I'm expecting the doggers to run through my land...If I hear them, I leave my stand and head to the nearest crossing...
