No, the Garand won't cure anything.
I started on one $50 Turk Mauser about 15 years ago. More followed, as some of these shoot very well. Then any other Mauser I could find, German, Czech, Yugo, Spanish and South Americans, then Enfields, then Carcanos and Steyrs, the Swiiss K31, Arisakas. Then I found Mosins and I have no less than two dozen of those now.
The Garand was always the big ticket item, so it came later. Solved nothing, because of course I needed a 1903 and a Carbine. Then a 1917. Then a Krag. Then a trapdoor Springfield. Then a Garand for match shooting.
This doesn't even count the pistols. A great uncle had left a Remington Rand 1911, then I found a Nambu, then a Luger, then another, then a Webley revolver...
I knew I had a problem when I sold off a few of my hodge-podge collection of safes to pay for a Vault door and a reinforced 12x12 concrete "bunker" in the basement, complete with wall racks, free-standing racks and even racks on the ceiling.
I also have an electric Cosmoline oven in the garage, made from an old metal file cabinet and 200 watt light bulbs for gently melting the grease out of wood stocks. Another friend/addict has a reloading factory in his garage that I helped pay for. A third built a Parkerizing tank.
Did I mention that I regularly drive the highways, stopping at small town pawn shops and leaving my card in case they get anything milsurp in? All the Estate Sale professionals know to call 'The old gun guy" to come over and identify and value any unknown firearms from poor Uncle Joe's estate, and I've gotten some nice rare items that way, but mostly old hunting guns I then sell or trade to feed the milsurp addiction.
