About This Magtech 5.56x45mm AmmunitionDo you want to turn your pieced out AR-15 into a surgical instrument? Then you need a round with a projectile capable of inch-perfect accuracy like only Sierra’s MatchKing can deliver. This 5.56x45 round’s 77 grain projectile features a boat tail design which significantly raises its ballistic coefficient, and as the result permits it to convey superior velocity downrange and better resist the effects of wind drift. This bullet’s narrow meplat streamlines its aerodynamic profile teriffically, and is a hollow point for added immunity to wind deflection. The bullet’s remarkable rotational stability is attributable to its extremely concentric jacket, as well as its core’s uniform weight distribution. Finally, a cannelure to prevent setback which could otherwise have harmed overall performance.
Magtech’s meticulously crafted and inspected components are well up to the task of complementing so accurate a projectile. These 50 rounds’ propellant loads are consistently measured so that they can always create virtually identical chamber pressures, and their primers are so sensitive that sunsets make them cry. You can make good use of their new brass casings at a reloading press as well.

I usually shoot 55 grain 5.56 in my AR15's. Got a Tavor which has 1:7 rifling and thought I would try 77 grain. It was already accurate, but this stuff was great. Can't give you group size, but shooting offhand and kneeing I was hitting 4-6 inch gongs at 100 yards without trouble.
