223 to hunt deer [What is the legal size of weapon to hunt deer?]

Can my son use a 223 to hunt deer?


The use of rim-fire cartridges is prohibited for hunting big game in Idaho.  There are no other restrictions including you are allowed to use 223 caliber rifles.  We do recommend hunters use well constructed bullets with enough energy at impact to make a clean kill.  Depending on the bullet weight, powder charge, distance, and bullet placement; a 223 may or may not result in a clean kill.
