[QUOTE="SBruce, post: 560028, member: 21068"] Yea, it's nice to get a fast one, so long as it's accurate. My fast 22-250 isn't nearly as accurate as my "normal" 22-250.? To try and answer your other question, yes I have went over book max in small increments looking for that specific target velocity. Sometimes because 2 or 3 different books don't agree on what's max, so we have to find it ourselves. Other times; with wildcat cartridges, there is no book info, then we've gotta find it by looking for pressure signs. Pressure signs are nothing to be taken lightly, and sticky bolt lift is an absolutely good sign of too much pressure. A marginally safe load at room temp can be dangerously through the roof on a hot summer day. Once I find what I consider max, I drop back by [U]at least[/U] a full grain of powder in 25-06 sized cases. Sometimes, in some cartridges, sticky bolt lift is actually way over max. It's nice to be able to duplicate factory ammo velocities, but if the accuracy isn't at least equal to or better than that same factory ammo, we're better off looking for the most accurace load, regardless of velocity...........no game animal will ever know the difference at reasonable distances. Best of luck, and be carefull when approaching max powder charges. Even seating depth or primer changes can change chamber pressures. [/QUOTE]
