I like white 1/2 inch glass shot and 5/8 marbles are fine for plinking and for me all around shooting. I dont bother to kill birds or small animals with the exeption of snapping turtles, snakes, the occational rat if I can get a sure clean shot. I find that marbles are just as devistating as steel ball. I favor Tex's Xpress Bands and never a hand slap. They are Xtremly Fast and render a terrific impact. I dont use anthing else anymore. My quest for the perfect band has finally ended.
