Mine was 30+ years ago. I was working for a gunsmith while finishing my degree, and a gentleman brought in a Interarms Mark X sporter in .22-250 with an older Western Field 6X scope. I was looking for my first project rifle, and hoping for a varmint caliber. The gentleman stated that the rifle wouldn't group and he was done trying to make it better. He wanted $125 for it. The gunsmith looked it over and told me I should buy it to learn on - we could always rebarrel it if needed. I offered the seller $100, and we settled at $110.
I took it to the range and found the previous owner was correct. Groups ran 4-5". Back to the shop for tools and supplies, then I spent an hour or so opening the barrel channel and bedding the action. Loctited the scope bases and torqued everything properly. Let it sit a couple days, then back to the range. It loved Federal 55gr factory loads ( anyone else remember Best Products?) and shot them under 3/4" at 100 yards off bags.
The gunsmith encouraged me to leave the 6X on it and learn to shoot the gun, so I did. I learned the ballastics of the .22-250, and held over as needed. I learned to estimate distance through that scope, and got pretty good with it. My longest paced-off shot was 527 yards on a ground squirrel - the crosshairs covered the target.
When that rifle was stolen from me, I replaced it with a Ruger M77V, topped with a fixed 6X. Still have it today.
