Why did you buy the rifle ?
"Any difference in performance between the .222 Remington Magnum and the
.223 Remington will fit neatly beneath one's fingernail without the slightest discomfort. This includes both velocity and accuracy capability."
"Today, it is a dying cartridge and shooters who own rifles in this caliber would be wise to stock up on cases and factory ammunition. "
Wish you good luck and have fun with it, but I would try to sell it if I could...........
