Best Uses

Load one magazine with Winchester Defender 5.56 for the house, and fire a few rounds first to check feeding and point of impact. The 64-grain bullet may hit a bit off your 55-grain practice zero, so confirm it. Barrels with 1:9 twist or faster suit this weight. Keep defense rounds separate from range ammo and swap them out on a schedule. Store the box cool and dry. Hollow point rules vary, so check local laws before you buy.
