[QUOTE="Lefty7mmstw, post: 2208769, member: 48043"] well.... I have both and they are rather close; the 7rum will burn more powder (with a standard chamber) and return a bit more vel. at the same pressure. My current 7rum is a short throat... about .2" vs. .5" or so for factory and for all intents and purposes runs like a 7mmstw charge and vel. wise. Both my 7stw and 7rum are 8" twist bbl.s so I'm spinning rather hard; the 7run eats the 175 eld-x pushed by 50bmg and my 7stw is running either the 183 sierra with retumbo or the 140 ab and rl25. I need to play with seating depth a bit more on the 183 and run them over the Oehler again but both are running 3K to 3100 on a 180'ish... The 140 gr 7stw load is 3350 fps as of a couple hundred rounds back. I'd go with whatever you can get a brass supply for and enough powder/bullets to feed and not look back... [/QUOTE]
