I have been doing a lot of research on this first time attempt. I have a 15 pound packer. I know time is just a rough estimate and you need to go to IT. I just want to make sure the time frame I have is correct so not to over do the meat. What I've read is its 1.5 hours per pound so I'm guessing smoke time should be around 22.5 hours. Please correct me if I'm wrong. Also dies anyone recommend any rubs or injections I should use or try. Any extra info I can get will be greatly appreciated.
