[QUOTE="Tex_Hunter, post: 2120255, member: 31749"] Are you about to blow your face off? Well lets review the details here: - Brand new rifle with little/no data: check - used load data from a completely different bullet/weight: check - Velocity WAY over book max (albeit for a completely different bullet): CHECK <- emphasis added here - Preliminary pressure signs on brass: check... again Yeah... Id agree with others that you are well on your way to being faceless, at a minimum please try not to do it at a public range where others could get hurt too. Seriously, read what actual experts have written on this topic: 1) load data is NEVER interchangeable between two completely different bullets/components 2) Velocity is ALWAYS your best indication of pressure 3) Pressure signs wont show up on brass/primers until you are already dangerously over pressure... again re-read point number 2 Something small like a 223 or a 308 in a decent action (read mauser/weatherby etc) is probably not that dangerous (beyond damage to your wallet) if you have a case failure... you are running almost 2x the amount of powder that the action will have to safely vent in a failure in an action that isnt as well designed. At a MINIMUM, at least you should be using data for your actual bullet/powder combo. Powder manufacturers post it for free, and load books are cheap, go buy a Hornady manual (they even post data for new bullets on their website for free until a new version is printed) and cross reference it with data from the powder manufacturer. If both of those say you are gtg... THEN and ONLY THEN are you safe. Just my opinion, worth what you paid for it. [/QUOTE]
