Just request .22 rimfire rifle, and .22 rf ammo, if you put .22 lr you can only buy lr rifle, as with lr ammo, no shorts, longs, bb/cb caps etc if you need them. .22rf ammo covers any .22 rimfire ammo from .22 bb caps to .22 magnum. A friend of mine requested bolt action .22 lr and that’s just what he got, he also requested subsonic hollow point ammunition, and that’s what he got as well. He couldn’t even buy or possess high velocity .22 ammo. It’s easy to unnecessarily restrict yourself simply by how you word it. No need to state what type of action either, keep it simple. Every unnecessary detail could be an unnecessary limitation.
