This question contains a false premise as it implies that Oswald's scope was "wonky" at the time he used his rifle to assassinate JFK. However, no one knows the condition of Oswald's scope at the time of the assassination. His rifle was hidden behind some boxes after the assassination (i.e. dropped). The authorities actually removed the scope to search for prints before testing the rifle. So it is impossible to say whether Oswald's scope was "wonky" at the time he used it to assassinate JFK and, for similar reasons, impossible to compare to any other situation. What we do know is that Oswald and Whitman received similar training in the USMC on how to use a rifle. Neither were a novice with a rifle and it was an easy shot for Oswald with his training with or without a scope.
I believe he used the iron sights. That was his only choice as regardless of shims at all, Oswald would have known that disassembling a rifle, placing it in a paper bag, and then assembling it inside the TSBD would mean the scope could not be trusted as it had not been zeroed in in its assembled state which is the only way to zero in a rifle.
According to Robert Oswald (in his book) LHO was home on leave around the end of February 1957. And they went hunting for squirrels. LHO was the only one who shot anything. It turned out to be a ring-tailed cat. These are related to the raccoon family and only grow to be between 1.5 and 3.3 pounds. Robert doesn’t elaborate on all the details and circumstances. But, generally speaking, one needs to be a pretty good shot to hit such a small animal in the wild.
Oswald flaunts his commie papers, pistol on the hip, scoped rifle... maybe a smirk or two.He's going for a look.. a 'vibe'Yo, if you can't be good, at least look good
