The Sierra #9377 is the 77 grain MatchKing hollow-point boat-tail in .22 calibre (.224″), the bullet that set the standard for .223 Remington and 5.56 NATO service-rifle and long-range match loads. This 500-count box is the non-cannelured version (Sierra sells the cannelured bullet as #9377G). Sierra publishes a G1 BC of .372 above 3000 fps (.362 from 3000 to 1700 fps, .343 below) and a sectional density of .219, and specifies a barrel twist of 1:8″ or faster. Match construction – not recommended for most hunting.
Cannelure or no cannelure?
This #9377 has no cannelure. If you crimp for semi-auto magazine use, Sierra’s #9377G carries a cannelure.
Will it stabilise in a 1:9″ barrel?
Sierra specifies 1:8″ or faster for the 77 gr; a 1:9″ twist is marginal and usually better suited to the 69 gr MatchKing.
Do I need a licence to buy projectiles?
