I hunted with an older Remington slide action rifle in 35 back when USAF assigned me to Wurtsmuth AF Base, Michigan. Every deer went down quickly, and stayed down for keeps.
Hey, Jack, I found your comments especially interesting in that I killed my first deer in 1964 while also stationed at the Wurtsmith SAC base, just outside of Oscoda, Michigan. I used a Winchester Model 100 rifle, chambered in .308, to get my whitetail.
As you no doubt know, the base has been gone now for a couple of decades or so. I still get back a couple of times a year to fish for smallmouths and northerns in the Au Sable River "ponds" (I often camp there at the Old Orchard park) and to salmon fish in Lake Huron, out of the marina in Oscoda. Much has changed over the last fifty years...
