Boomer has compressed a tremendous amount of excellent information in his article. The sad part is that the young hunters who could most benefit from it, probably won't give the article a second thought.
As he states, a big game hunter does not require a high power scope. But, modern hunters are loading their rifles down with huge scopes. A rifle must be a pain in the fanny to carry, and use, with such awkward eqipment on it.
When decent scopes came along after the war, they were, as Boomer has pointed out, highly praised for the fact the crosshairs, or reticule, appeared to be on the same plain as the target. The most experienced hunters of the day quickly decided a low power was what was best. Vast numbers of hunters used the sturdy, clear, well made Weaver K2.5. For prestige you got the instrument most used by the pro hunters, the Lyman Alaskan, 2.5 power.
And when was the last time you saw a shooter slip his arm through his sling, take an extra wrap around the lower arm for a tight sling, then sit down with elbows resting on knees, for a very steady field shooting position.
The trouble with all of this Boomer, is that we are dating ourselves! Oh well, I am glad to have been an active shooter and hunter during the glory years of the sport.
