[QUOTE="goodgrouper, post: 90058, member: 2852"] Jerry, I appreciate your post and value your opinion. However, I will have to agree to disagree with you on this subject. I use Benchmark (a so called extreme powder) in my 6br, and Varget (extreme powder) in my 6br improved fast twist, and H4831sc (extreme powder) in my 22bjbft, and H1000 (extreme powder) in my old 22-284, and have developed loads for other guns numbering in the several dozens in which the rifle's preferred powder was Hodgdon, so I know a little about these powders. [img]/ubbthreads/images/graemlins/wink.gif[/img] My current 6br loading from summer is now shooting 65 fps slower, my 6br improved is now shooting 78 fps slower, my 22 bjb is now shooting 130 fps slower, and my winter load for the 22-284 lost 175 fps from summer loads!! Now, if you are just out shooting at large or medium sized targets at intermediate ranges, even the 65 fps difference in the 6br is still going to allow you to hit your target while being none the wiser as to what happened. Only chronographing these loads in both temperatures will show you a difference in velocity. 65 fps drop might still be minute-of-coyote, but if you have a hot rod that will only shoot well 20 fps either side of x velocity, you are now going to have to find a new charge weight! Incidentally, my 6br will shoot well (.5") with almost any charge of Benchmark, but if I want the almighty .25" group, it has to be custom tailored load for the conditions on that very same day! THis is why the 100 yard BR competitors [i]load their ammo on the spot a few minutes before the match starts.[/i] ANd by the way, one of the largest producers of custom, non traceable 50 bmg ammo used by our snipers in Afghanistan right now is located just a few blocks from my home and they "tinker" with loads just the same as us hobbyists do to chase that magical pressure that a specific rifle likes.
