I'm starting to think this could be fun... have just been reading some American forums and a bloke cut a 270 to 16" and was getting 2780fps from a 130gr sst being pushed by H450 (2209). As has already been pointed out I reckon some 2208 could improve on that. A 150gr LRAB being launched at 2600 would hold 1000 ft lbs to 650 yards... hmmmmm
