I shot lead lead in #4,5 and 6's for years and eventually settled on 5"s. When Remington loaded the Heavyshot I shot #5's in an Undertaker HS choke would put over a hundred in 10" circle at 40 yards and 80 to a hundred in 10" at 50 yards. These would smoke a turkey but Remington and Heavy parted ways. So I shoot Nitro's in straight heavy 5's now through a Rhino 660 and get around 150 in a 10" circle at 40 yards and around a hundred at 50 yards and this load will smoke a turkey. But the shells I got last year didn't do as well probably about 20% less in pellet count. The shot size actually looked bigger. They still smoked turkeys though. I am thinking about trying the 4x5x7 loads this year.
