Lol. Some of the best snipers in the world have said that they could not replicate those shots, and they were alledgedly made with a dollar store with the most defective scope ever. I'm not aware anybody replicating the shots. I know of one experiment in which an olympic sniper accomplished something similar... from a height of the third floor of the school book depository.
And I could accomplish something relatively easily that it would take thousands of trials to
replicate.
I can flip a coin 20 times and whatever sequence I get would take roughly a million trials (2 to the 20th power or precisely one in 1,048,576 trials) to
replicate precisely.
You're asking the wrong question.
Nobody needs to
replicate the shooting exactly. All they need to do is put one shot in the head or through the heart. Any shooter who accomplished that accomplished what Oswald did.
Oswald didn't set out to perform the shooting a specific way, with one miss, one bullet going through two men, and another hitting the President in the head. That was the happenstance results of what he set out to do.
Oswald set out to kill the President. How many of those trials you're familiar with made at least one kill shot? More than 50%? That's really all those trials should be attempting to accomplish.
And most adequate shooters could accomplish that feat.
I used a 1917 Mannlicher Carcano (Oswald's was only 18 years old) in 2015 to shoot at targets from a bench rest (essentially what Oswald had from that window) and scored four hits on the target in six shots - three in the body and one in the neck. My weapon was more than five times older than Oswald's and still accurate enough for the task. Oh, and one more point. As a city kid, I had never shot a weapon before in my life. That was the first - and to date, only - time I ever fired a weapon at a target. Yeah, my target wasn't moving, but each of my six shots was at 100 yards, each longer than Oswald's longest shot.
And as to Oswald's weapon, it was tested and found to be as accurate as any modern military rifle at the time. The scope could not be sighted properly when found, but Oswald dropped it on the floor between some boxes and that could have caused the scope issue after the shooting. In addition, the iron sights were perfectly adequate for the shooting; Oswald trained at 200 and 500 yards in the Marines. And this shooting was - at its longest point - just 87 yards - about 1/6th the longer distance Oswald trained at only a few years before.
Your arguments are failures.

EDIT: I see TomTomKent made the same point I made about the replication aspect of the feat. Killing JFK is relatively easy from that location with that weapon. Replicating Oswald's feat is a different question - and the wrong one - altogether.
