I think I have received about 5000 pieces of brass from him so far. Out of 5000 pieces none have had any issues. Now, statistics would rule that he should have an error greater than the factory's which is about 0.5- 1%, and yet his attention to detail has made the error rate 0%. Now, I like the large companies brass, but Matt's quality is second to none. I cannot speak highly enough about his service, quality, and personal manner. He is a great guy to work with and I'll continue to steer my business his way. I think you should too.
