Underwood Ammo combined with Hornady's InterLock projectile is a devastating and superbly accurate combination. The InterLock ring is exclusive to this projectile, which offers high weight retention due to the InterLock ring locking the core and jacket together under the stress of expansion. The InterLock retains high mass which offers high momentum after impact and transfers that energy into the target. Underwood Ammo loaded with Hornady's InterLock offers a consistent, accurate, and superb loading for classic and modern .303 British rifles.

As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

While taking advantage of our state of the art testing equipment, this high performance ammunition is field tested using popular, real firearms that our customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, we stand by our product 100% and will make sure the customer is satisfied with every purchase.

This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
