[QUOTE="Jason Price, post: 30225, member: 512"] I also have a couple of 7 RUM's, but can't seem to pass the 3700 fps mark very much with a 140 gr NBT even in one that has a 30" barrel What I would really like to do is put a 120 to 130 gr bullet out in the 4000 fps neighborhood - I have a .257 STW that does 4300 fps with a 100 gr NBT in a 28" barrel - Why would it not be possible to split the speeds and bullet weights of these two to an average of 120 gr @ 4000 fps? I know internal ballistics aren't quite that simple, but to this simple country boy it seems practical. A couple of questions: Has anybody got or tried the "Load From A Disc Program" Can somebody explain this item in the Barnes Reloading Manual Number 3? Page 280 Standard 7mm Remington Magnum 140 gr XLC BT Max load of Norma 204 at 67 gr VELOCITY OF 3773 FPS ??? JP [img]images/icons/smile.gif[/img] [/QUOTE]
