Time and time again on this forum we see peoples plea for re-loading data surely if one begins reloading then along with the dies, etc to reload said cartridges one also buys, begs, borrows or steals a suitable reloading manual .
Not todays reloaders it seems they rely upon others to do so and look up the information and hopefully share is accurately through the forums. I wonder what would happen if due to a typo or incorrect information being posted that a cartridge is loading with an over laods and some damage or injury results .
There were reports of an error on one of the Powder makers web sites in their loading data which resulted in damaged guns. Of course once reports came in a couple of clicks and the error was corrected but in doing so it removed the evidence so claims became almost impossible to follow up.
With a proper printed manual more care by the writers, company and publishers must be taken as they cannot correct an error with a couple of clicks once it's printed and in circulation.
A reloading data manual is not that expensive really and often has much more than just loading data inside. For beginners they often take you through step by step reloading. They might just help printed books hang on longer and you might even learn something by reading one so go ahead and get one at least if your going to reload cartridges. Of course it will mean any mistakes are solely down to you.
