I had only shot about 5 of my gc'd .223 boolits when I noticed this! One more inch to the right and it would have gone belly up. The dent is deeper than it looks. I think I am done casting and shooting 22 cal. Am not getting any accuracy or constant velocity and now this. I am now loading and shooting copper plated .224 39 gr. boolits that were made for .22 magnum. Much better accuracy
