No, but SAAMI specs and published reloading manuals are the closest thing to a bible that handloaders have. They are there for a reason and for that same reason is why ammo and firearm manufacturers follow them. While I know in recent years some specs have been softened, they are still something responsible handloaders respect and use. Their guidelines, while maybe not cast in stone, are guidelines that keep our sport safe. As we both know, safety is paramount with reloading. I may not need to be told about the "other" sources of "well proven" information, but maybe other readers of this thread, like the young and inexperienced I mentioned before, could benefit from this knowledge.
It always amazes me that some feel the need for derogatory adjectives and name calling when trying to make an argument to support their opinion, and yet we call this "The High Road". You can take this to the bank 35W, everything to do with handloading for existing cartridges, has already been proven. While I have no problem with folks that feel the need to push the envelope with their own firearms, knowing full well the risks involved, I do have a major problem with chest pounders making blanket statements on the internet that it is safe and appropriate for everyone. To belittle folks that stay within the parameters of responsible reloading is only asking for an accident to happen. If you are as experienced and knowledgeable in handloading as you want us to believe, you know as well as I do, that some newbie, after reading rants on the internet about over max loads being perfectly safe, and one is a drooling worrywart, afraid to leave mamma to not at least try them, is gonna do just that. Maybe you want to applaud that newbie to reloading that fills his cases to the brim because he is not as you call it, "a fear-mongering, hand wringing, sniveling worrywort", but I won't, and I'll let you sit next to him at the range when he tries his new loads. I'll also continue to use my firearms and ammo within the specs and parameters they were intended. If I need to have something more powerful, I'll just grab a bigger caliber. Pretty simple, it's why they now make bigger calibers. Besides......like some others, I don't get that big a thrill outta beatin' Pintos and Gremlins.
