I bought 25,000 1 1/2s a few years ago at the end of the O'Bama shortage. A case from Midway who had them on sale with free hazmat and shipping. I use them mostly for .38spl. I don't load any light .38spl, mostly +P and Heavy +P and have had no trouble with splits or piercing. I am going to load some standard 9MMs and see how that goes. I thought I had bought 50,000 but opened the big box and checked there were 5 boxes of 5,000 in the large box with a lot of styrofoam blocking between the boxes......
