I really like that Federal LE buckshot. It keeps the patterns remarkably tight, which is the key to its effectiveness. Back in the day I shot a deer with a standard 9 pellet 00 load at a range of about 15 yards. Terrible performance. The deer was standing in a logging road with nothing between me and her. When I stood up, she skidded to a halt and I popped one at her. I knew she was hit, but she ran off. We found her about 100 yards away. One pellet broke her leg, another pellet went into a lung. Yeah, we recovered her, but I quit hunting with buckshot that day.
On the other hand, this Federal load is the cat's meow. When we qualified last year, we were using the 00 LE 9 pellet load. Our cruiser 870s would keep all the pellets inside the 8 ring of a standard B27 target at 25 yards. By the time the qual was over, the target had a big ragged hole where the 8 ring had been. Great performance.
