We may well be tied. This is when I was in college at Slippery Rock. Not sure when I got my first Pa. hog but probably sometime in the 1950's.
I shot my first groundhog in 1959 I was 17 years old I used a 220 swift pre 64 Winchester Model 70 varmint with a 15x Unertal ultra varmint scope and I was hooked for life.

Built that rifle with a Herter's laminated stock, Enfield action, Douglas barrel and RCBS dies. Reamer came from Tony Vitale in Branchton, Pa. 6mm/284 - quite unique back then. Oh - that is a Unertl 2" Ultra Varmint. Built it all way back while I both worked at a gun shop and put myself through school.
This topic brought back memories so I dug the picture out and others.
