I've been reloading for years mainly using Zero bullets in 9mm and 40S&W. They're of good quality and I'm pleased with their performance. Recently they're out of some weights that I need. I don't shoot lead or plated. I noticed that Precision Delta offers the same weights, often at a significantly lower price. How does the quality of Precision Delta compare to Zero (consistency of weight, shape, length)? Are the jackets as thick? How about performance?
