Id be interested in the results.Back in the late 70s, I bought a wooden case full of very old 22 short hollow points. Parts of disintegrated whiteboxes and green and red Remington boxes were in with the ammo. Bullets are plain lead, no plating. Fired a bunch of them in my wife's High Standard flite king 22 short pistol. Worked fine then, might dig them out and try some more.
