Unless I was precluded by law from using a semi-auto rifle in 223 to hunt with, such as in PA, I can't see the lure of a pump action 223.
I once had a NIB 760 in 223, purchased at J.W. Barber's Discount Store in West Lebanon, NH, back in the late 1960s for under $150. My Father thought that it was a waste of $$, the wrong vehicle for a 223, so he convinced me to trade it for a NIB 660 in 222 at The Green Store in North Haverhill, NH, just a few months later.
