I think I bought my first gun the day after my 18th birthday, 11/22/68, and Argentine Mauser DWM in superb condition. Never fired it just had it. My brother, now passed was a re-loader and a lifetime member of a local range. Anything I bought we made ammo for it ( he was in DaNang when I bought the Mauser). How about .256 Newton. Had my own wildcat based on a 38 caliber rebore of a scheutzen rifle with a corroded bore, originally 8.15X46R. Still have it, used to shoot MOA 5 shot groups at 100 yards with the original peep sight and hand loads, which could be just using the case as a chamber seal with a paper patched bullet, either cast or jacketed, a new primer and measured charge.
I lived to buy the unusual, then to shoot same, then got bored with it and let it go. I guess if I owned 250 cars since the mid 1960's the guns followed the same general pathway (topped out at close to 90). Lots of times it was the deal not the gun, a M48 Yugo Mauser with a cosmoline fouled bolt assembly for $15, sold for $200. Doubled my money in 150 feet at a gun show even more with some Richmond Va musket parts for $20 (garage sale), sold for $375.
The cars provided me with free transportation, smoking Valiant for $400 with 40 k miles, cleaned the PVC valve and hose and the crud on top of the head. Oil consumption dropped from a quart in 400 to a quart in 1500 miles. doubled my money a year later.
Now my ammo selection is 44,38 and 22 so the guns follow that controlling factor. I shoot occasionally. Old eyes and unsteady hands mean accuracy is only a figment of what it used to be. Now that income is where I need it to to be, I can buy just about anything if I want it bad enough, but our living space is much smaller than it used to be so my accumulations are limited.
I stay in shape by playing pickleball, for free and if I live close to my fathers age I Have almost 3 decades left. He made it to 103.
