Super cub - I had a M760 in .223 from 1973 for 15 years or so. Never hunted deer with it but used it extensively for chucks and jack rabbits. It was very accurate with home made bullets a friend made (3/4" groupings). Quit using it much when the chucks and jacks pretty much disappeared from around here.
It seemed to be a .22 bore in a standard weight barrel so it was almost like a semi-sporter. A guy finally bought if from me after about 3 visits and trying to get me to reduce my price. On his last visit I finally told him if he didn't buy it I would put it back in the safe and never offer it for sale again. I could almost see the moths flying out when he finally took out his wallet.
