I uses Superior for my 7x57 when I first purchased it and was new to reloading. I had 40-60 rounds made up as a sample pak and finally settled on 160 gr tsx load. I purchased another 60 rounds. They were 3/4 inch loads from a rifle, I have only been able to get 1 1/4 to 1 1/2 out of! I've kept the ones I have left to shot every once and a while to make sure I didn't screw up the crown or something. Good ammo by any measure.
