[QUOTE="codyadams, post: 2522767, member: 87243"] Ok, just shot the 140 SBD II's in a 25" .270 Sherman (.270 win with a shortened neck, less body taper and 40° shoulder) tonight. For reference, another 19" I loaded for maxed at about 3160 with RL26. Also, this gun has always left very faint ejector marks even on very low pressure loads, for this one I look at how prominent the ejector marks are, as well as primer crater, and feel for bolt lift. This is without the supressor attached, that may add 10-20 fps, not much.
