[QUOTE="Lefty7mmstw, post: 2219885, member: 48043"] The only thing giving the 7rum any real advantage over the 7mmstw is the extremely long throat that a saami reamer has in 7rum. they are both so overbore there is little real difference in real world velocity between the chamberings given the same apples to apples comparison one should really give to hotrods like these. Pick the same throat for both: ie. 1 or 1.5 degree lead angle and .2"... .4" length... use two barrels of the same brand/ twist/ etc.. You will see less than 3% gain from the 7rum mathematically... One barrel acting fast with a given powder and the next acting slow can more than negate the difference ( or accentuate it a bit)... This thread has turned into campfire chatter and really does no service to either cartridge. [/QUOTE]
