The Carcano was not designed to have a scope. A scope does not work well because it can’t be mounted on the top, without preventing the bolt from working. So, the scope won’t help the rifle aim high, which is necessary to take into account gravity, but will aim high and to the left.
Also, the scope added to the rifle only added a few dollars to the cost. They could have not zero-sighted the rifle without losing money. So, the rifle probably did not have shims installed with the scope.
Why sell a rifle with a scope? Because a scope looks cool. It makes a buyer think he looks like a real dangerous shooter, who really knows what he is doing. This may have been the reason why Oswald bought the rifle with a scope and kept it on.
Also, as I recall, an executive with the company told WC investigators, that the scope added to the rifle was not zero sighted. The scope was just slapped onto the rifle. The executive would have no motive to lie, to make his company’s products sound not as good as they really were.
So, it would unlikely that a company would add a scope, go through the expense of zero-sighting the scope, sell the rifle/scope at a lost and claim they never bothered to zero-sight the scopes. That makes no sense.
All this is irrelevant because Oswald could just simply use the iron sights. Oswald was trained in the Marines to shoot, not with a scope but with iron sights. At ranges of 200, 300 and 500 yards. Much further than the maximum range at Dealey Plaza of 88 yards. And the scope does not prevent the iron sights from being used.
Also, the iron sights help with the accuracy of the second and third shots, at z222 and z312. The target is rising and at the short ranges, the rifle would miss high,
at a stationary target, but provides a lead that in theory should hit the target within two inches for both shots.
More details on this are in a post I made six years ago, which disappeared when all the posts at this site disappeared, but which I have reposted.
https://www.jfkassassinationforum.com/index.php/topic,3522.0.htmlThese figures are reasonably accurate. Since making this post, I have adjusted my estimate of the limousine at z312 from 9 mph to 8 mph. And I use the ranges of 65 and 90 yards instead of 63 and 88 yards because the ballistic calculator program only provides numbers for every 5 yards. I could have extrapolated but did not bother. My 2016 estimates are still pretty accurate.
My expertise in rifle shooting? None. But I am good at math and I think I have entered the appropriate settings for the ballistic calculator and my analysis is pretty good, I believe.
