Get all of the reloading manuals and read them from cover to cover. Many of the folks who do the write ups on each cartridge are experts and you will find a lot of info about the whole shooting industry. Never load to many shells at once. You can get burned out and careless. Its a great hobby and has given me much joy and passed many cold winter night In the Dakotas. Also there are some great vidios on reloading from Sierra and many other companies. I should have spent some of that reloading time learning how to write and spell.
