I recently got a reloader for christmas today, along with a copy of Lymans Shotshell Reloading Handbook 4th Edition. I have the reloader all together and I am also going to get a set of scales tommorrow so I can get everything fined tuned. I have thousands of once fired Remington Primier Nitro shells so I figured I would start with them. I tried looking them up in the Lymans handbook and I dont understand the book at all. I couldnt find the shells anywhere in there. I really dont understand the book, and where I can find the shells in there. I am brand new to reloading so any help or tips will be greatly appericated. Thanks alot.
