Winchester engineered it for high-performance in both suppressed and non-suppressed guns, too. Try it in your .22LR and you won’t be disappointed with the results.You must be 18 or older to purchase ammunition for use in a shotgun or rifle and 21 or older to purchase ammunition for use in a handgun.
