Ditto what Oldtimr stated! I have an old bolt action Savage that I rarely use up in northern MI unless the weather is real nasty and the shot will be close because it has open sights. I quit using Core Lokts quiet a while back and went with the Leverevolutions not long after they were introduced by Hornady. They shoot more accurately and can be used at longer distances if you have a scoped rifle just in case that big one is out further than you would use the older ammo.
