If you are asking if buds can send you 22lr ammo you buy online, yes.
If you are asking if you can mail/ship ammo to a friend or family member, the answer is yes with a few restrictions, like it history be sent ground and cannot be loaded on a plane, check with the carrier for all requirements to ship ammo.

Michael, yes, Bud's can ship .22 ammo to NJ. I live in the Peoples Republik of NJ 😫 and have had .22 ammo shipped right to my door. That is for the time being, Biden wants to end all internet sales of guns and ammo.

Michael, yes Sir it is legal for you to receive or ship. If you are shipping, UPS Ground Service is the preferred method. Just print off a couple of ORM-D tags to tape to the box. Cheers and stay safe!
