Tried some 173's and 200's with 11gr Unique. Too cold and windy to do any accuracy tests, but they functioned well through the action and printed more or less in good groupings way out there near the big rock on the 100 yard berm. (Iron sights.) Shot about the same as the 200's at 10gr (found a bunch that I'd loaded five years back for a .35 Remington I'd not gotten around to shooting.
