I have the exact same rifle, but a 1950 model. Even has the original Weaver K6-1 scope on a Redfield one piece base. My grandfather bought it new and had it on the tractor for shooting 'yotes (he raised sheep so his hatred for coyotes burned bright). I eventually inherited it. I have the original stock for it but put it into a Boyd's laminate to help protect the original stock from dings and scratches.
I did some load development for it years ago using H380 and Sierra 55 grain bullets. I ended up getting some really good groups with that rifle with the best being .3" 3-shot group at 100 yards. I figured that was probably good enough so I quit while I was ahead.
Grandpa used this Swift to take everything from 'yotes to moose (when he didn't want to carry his pre-64 M70 in 300 H&H) I even have a little adaptor for shooting .22 rimfire out of it if I wanted to. They changed the laws a number of years ago up here so you can't use a .22 cal for big game hunting. This one has been relegated to shooting 'yotes and punching paper.
