Tested several of the NSA .30 cal weights in .300 and .303 in my Vulcan 3 with 700mm barrel. Set reg pressure to 125 bar (Lane Lancet MK9) shot at 50 yds.
(.300) 47.2 gr slugs at 919 fps. was .744".
Without changing any settings:
(.303) 47.2 gr group size .619"
(.300) 49.5 gr group size .639"
(.300) 61.5 gr group size .701"
(.303) 61.5 gr group size .569" without one flier which opened it up to .956"
(.300) 59.4 gr did not do well in my rifle. Grouped at 1.384"
