My 'minimal gunner' friend (he has one gun, a 9x19 pistol) brought over some .22LR ammo his deceased dad had stored in the cellar a few decades back. I had forgotten the labeling Remington used to use. In one box of Remingtons the case heads have a large U in the center, surrounded by Hi SPEED. the box states that the ammo has non-corrosive Kleanbore Priming. The box of Super X is Western Super X, and states prominently: Superior Accuracy Positive Functioning 40 Gr. Lubaloy Coated Bullet Special Dry Wax Lubricant I'm thinking that .22 rimfire ammo used to be a 'bigger deal'.
