308 Norma Mag…

Way too generic of a request without some information about the rifle and the twist rate. This has been discussed on other forums so there is information available with some guidelines from you. Safe information from the reloading manuals is still safe no matter the time frame. They would have been sued if the data was too hot. Barnes 1st edition is the only printed manual that got called into question.

Best regards.
