I've shot many hundreds of rounds of NSSA style skeet with my 12-gauge Fox-Sterlingworth Ejector Skeet & Upland Game Gun, mostly using my 7/8 ounce 1200 fps reloads. I've run a couple of 75 straights with it but have never been able to get that fourth round. Back about 1987, I shot the only 100 straight I've ever shot with a 28-gauge using my Winchester Model 23 Classic!?! Gave me a brainstorm to try it in registered competition and I fell on my face!! I shoot some pretty good skeet scores with old square-back Remington "The Sportsman" autoloaders, and Model 31 pumps but I probably do my most consistant work with Browning Superposed New Model Skeet Guns in 20- and 28-gauge.
