I don't know how or why Accurate changed their data. I got my info from Lee's reloading manual which matches the data from Accurate's edition 3.3. The COL listed is 1.095 so mine is actually slightly longer than the data says. I'm not saying ignore the published data by any means but realize they are guides. This a perfect example. I've used my load for years with no problems and see no reason to change. I have no idea what kind of velocity I'm getting, never rally cared.
