Received my copy of Graeme Wright's book Shooting the British Double Rifle and let me just say it is a treasure trove of useful information. I have two rifles now, funny how they follow you home, and I'm planning on trying to work up some different loads for them. The info in the book covering powders and regulating will undoubtably make it more fun and rewarding without wasting a lot of time, effort and money. A nice looking book to boot. Looks good on my coffee table. I highly recommend it.
