Meta Quest 3 & Ace VR Handgun….

Don’t have airsoft or BB guns & don’t want to freeze to death in my backyard 6-7 months out of the year

That is the beauty of airsoft. Take a cardboard box and put some wadded up newspaper in it, tape it closed and shoot the hell out of it. If the bb's start going through add more newspaper. When you run out of bb's open the box and they will be there waiting for you. They will usually penetrate 1 layer of cardboard but the newspaper and the second layer of cardboard are just too much to get through.

Also, hang a piece of carpet in a box. Much easier to retrieve the pellets.
