As scope mounts go, Charlie O'Neil's was one of the best �
but
Iver Henriksen put one on his favorite elk rifle, then packed-in to the South Fork of the Flathead (some years before there was any road there).
The first day after he arrived in camp, he discovered that the dot in his reticle was hanging loose on a broken spider web "like a [bleep] cherry on a twig."
Charlie's mount wasn't easily detachable � a fairly major shop operation.
