Ok looking for

straight from Mr. Google.

Can't fit batteries into such a tiny cartridge. Can always use the boresight kit I posted. Or if its a lever action or bolt action, remove it and you can eyeball through the barrel itself and adjust the sights while the gun is secured. Windage will be close and elevation just a bit off. I misread your original post, thinking you were talking about a REAL cartridge, like a .225/5.56.
