[QUOTE="MallardAddict, post: 1211629, member: 3830"] I guess I am confused with your reply, what clear pressure signs am I ignoring? Every round I have ever loaded has been exactly how the books say to load them. I always start at minimum suggested loads and work up carefully. I started my load testing at 68grains of R22, which is the starting load for that powder in my hornady book. I worked up to the current loads in 1 grain increments until 70 grains which is mid book, after that I worked 1/2 grain increments. All loads were done in groups of 10 rounds and all shot as 5 rounds groups over 2 differnt chronographs. In the interest of clarity I loaded: 68, 69, 70, 70.5, 71, 71.5, 72 and 72.4. In every single one of these loads 2 differnt chronographs showed I was faster then book speed by 200-225 fps. I am not a professional, but took my time loading, prepping brass, weighed each charge, measured each rounds COAL etc. I'm not sure what else I can do as a casual shooter to be any safer. I asked the question because the speeds seemed high to me but nothing i can see in my brass, how it chambered, extracted etc was any differnt from any other round I have loaded. I am all for learning and advice, but please don't assume I am new to reloading or looking solely for speed. I value my life and safety too much for that crap. As an aside I called Hornady and the tech said he has heard of many people getting 3k from R22 in a good barrel. [/QUOTE]
