Silver bead, Remchoke Xfull, 2 1/8 oz of bismuth #4 in 26” SP10.
Kinda sucks if you have to carry it several miles but you asked for effective.
Also killed a truckload of gobblers with a Mossberg 185 3” boltgun with a polychoke and a camo paint job. 3” unplated Winchester SuperX 6s with the choke a 1/4 turn past full. It’s a shredder and kills at both ends, ugly as used dog schit anyway so you don’t mind dragging it around crawling through the rocks and cactus.
