Sierra’s Tipped GameKing at 140 gr in .270 Win (.277) (part no. 4440T) is a hunting boat-tail hollow point built around an optimal jacket wall thickness that controls expansion while retaining weight. Sierra opens a pocket under the polymer tip that drives the lead core to expand instantly on impact, while a tuned ogive and boat-tail base give it an high ballistic coefficient for stable flight downrange. This is a component bullet for handloaders, not a loaded round.
