Back in the day I shot 1-3/8 oz of 5s at 1330 fps. Now I'm only shooting 20ga. Tough to beat Kent 3s and 4s at 1550. Like Rick I shoot a lot of 5s but have found the Fiocchi speed steel work better for me. I think the current high speed 20ga steel loads are a lot more effective than the old 1 or 1-1-1/8 oz lead loads.
