I had the chance to talk with Steve a few years ago about this article and gained an insight to reloading. I… had assumed that they were close enough, but the devil is in the details. Steve’s website contains a wealth of information on Military firearms and reloading information.
Steve fully explains the difference, safety procedures, and proper checks on his website http://www.303british.com/id36.html
Also check out his website and book store.
