Before I begin to reload my own shotshells, I am reading books, posts, etc., before I even purchase the reloading press. A guy at the local skeet/trap club will sell me a MEC 600 jr. to get started. I am reading this with interest as I also have damascus bbl guns and I want to keep pressures between 5000 and 6000. The first reloading book I purchased was yesterday, "The Complete Reloading Manual for the 12 Gauge Shotshell" published by Loadbooks USA, Inc. On the cover it claims to have 10,000+ proven, tested loads. Is this an okay book? Are there better ones? So far in this post, I've seen 7625, PB, and 700x powders listed. Are these considered "slow burn" powders? Just looking to get started reloading. Thanks for the help and knowledge shared here.
