⚠️ Recall Notice
Winchester recalled only two lots of X17HMR1: lot numbers ending in NB51 or NB61. Winchester states that these lots may contain no powder charge, which can leave a bullet lodged in the bore. A subsequent shot could damage the firearm and cause serious injury.
Do not use X17HMR1 from either affected lot. Stop use and contact Winchester at 844-653-8358 for the current return instructions. Other X17HMR1 lot numbers are not included in this 2019 recall notice.
