[QUOTE="Lefty7mmstw, post: 992454, member: 48043"] Not possible at sane pressures even with the best powders available today. First, get a chronograph, second, read this thread. Barrel twist rate means less than 100 fps here so please do not try to hang your "velocity" on a slower than normal twist. We've had a couple of guys here with 11" and 12" twist stw's; one offered me his barrel for free a couple of months back; we decided that slower than a 9.5" twist was better as a tomato stake than a rifle barrel. His was about 30" and 11" or 12" twist. When I use up my 10" twist lh remmy's barrel I'll be in the market for one in the 8"-9" range so it'll be good for up to 180 grain slugs.
