The PMC X-Tac Match .223 Remington 77gr OTM (brand part no. 223XM) loads the legendary 77-grain Sierra MatchKing open-tip match bullet for precision and competition shooting. PMC pairs the high-BC MatchKing with boxer-primed, fully reloadable brass, delivering the shot-to-shot consistency match shooters demand at distance. The small exposed tip is a byproduct of the match-grade jacket process, built for accuracy rather than expansion, and the heavy bullet rewards fast-twist precision barrels. Among rifle ammunition, this X-Tac Match load favors competitors chasing tight groups at extended range.
