--The action of Matt's Springfield sporter was made in 1918, some 92 years ago. When he rebarreled it to .35 Whelen, he chose a cartridge first introduced in 1922.
--Apparently that Featherweight Model 70 action sat around the Winchester plant for a couple of years before they screwed in the brand-new .243 barrel in 1955. That was well over a half-century ago.--Ruger introduced the fine, three-screw Super Blackhawk .44 in 1959 and discontinued it in '72. That powerful and perfectly serviceable sidearm is likely somewhere between 40 and 50 years old.
A while back, I wrote about the difference between obsolete and obsolescent, which is sorta kinda on point. There are those who'll wonder how Matt could possibly make an efficient hunt with those ancient guns . . . .
Matt, convey my greetings to your host. Good hunting and safe home.
