Here's where I am on the shooter:
Oswald had a 4x18 scope on the 6.5mm Carcano Model 91/38 rifle; it was an Ordnance Optics scope, 3/4-inch tube, an 18mm objective lens, a simple crosshair reticle, and basic windage/elevation adjustments. It was a low-quality, imported scope, side-mounted on the rifle, with poor optical clarity and a misalignment that required shims to correct during FBI testing. Its field of view was approx 20 feet at 100 yards.
A few points in no particular order:
- That's a pretty narrow field of view. Most "more modern" scopes with 30+mm objective lenses will provide 3x+ field of view at 4x magnification.
- The scope was side mounted and "shimmed" in place
- When tested by the FBI; the rifle was not zeroed
- Both Zeroing and aiming a side mounted rifle presents challenges
- The iron sights were still on the rifle
- The best data I can find on the timing from 1st shot to final shot was "likely 5.6 seconds (accepted by the Warren Commission)"; but could be as long as 8 seconds based on some views.
My bonafides: I shoot a fair amount. I qual'd as Marine Expert as a young man....no special marksmanship training beyond that from the military perspective. I never used a scope until about 10 years ago. So everything I shot up until then was with iron sights. In the last 10 years I have spent a lot of time shooting with scopes. I shoot a lot to be proficient for the type of hunting I do. I don't really view myself as a great shooter; though I have made my share of great shots. I have trained with elite shooters...they are spooky good. I am confident in saying I am well above average and well trained; but I would not say "elite".
I practice on ranges with varying scopes and some specific exercises; shooting; cycling the bolt, re-acquiring another target; and placing an accurate round on that target; with someone with a stop watch on me. The goal; shoot and reacquire and accurately shoot in less than 10 seconds. The "moved target" being anywhere from 25yds to 500 yds away. This simulates shooting an animal; not knocking it down with the first shot; and having to shoot the wounded animal as it has moved away. So, basically, what the lone gunman shooter would have had to do.
I score very well on getting an accurate round on the followup shot within 10 seconds; by accurate I mean on anything from a 6" to 12" plate depending on distance to target. ..usually 8". 80% of the time...some days (especially with little wind) better. But consistently 8 of 10 within 10 seconds across a wide range of distances. Many times in under 5 seconds...but often clicking the round when the counter says 9....mostly now I use a Z8i 2.3-18x56 scope...so great field of view on picking up the second target (about 20m field of view). I don't have to worry about my scope retaining zero even with heavy abuse. I don't have to do anything special holding a different distance or for wind; my BRH reticle makes that doable.
Really great post. Thank you for your service and sharing your expertise with us. I do have a few questions for you.

As a Marine, Oswald struggled to maintain "Marksman" status...his skills degraded during his tenure according to records; he qualified with the M1 Garand. He scored 191 at the range in 1959; anything below 190 is failing.
That does leave out that he did qualify previously as a Sharpshooter at 212. Not an expert like yourself, certainly. His shooting in 1959 was after he had been convicted at two separate court-martials, and he was ready to get out of the Marines and was already planning on defecting. He spent 20 days then 48 days serving hard labor in the brig for shooting himself then months after that, assaulting a NCO. As he was already planning to separate (if the USMC didnt do it for him first, who knows how much effort he put in. Maybe that was the best he could do, maybe he did the best he could and he barely made it. There is no way to know. But we do know that he was able to qualify as a sharpshooter (middle level between Marksman and Expert) at one point in his career.

Friends/acquaintances told the Commission he was a poor shot
Here is the actual testimony from Major Anderson, a 26 year Marine veteran of WWII and Korea.

...now, the magic shot was from about 88yds...so a far cry from trying to qualify from 200, 300 and out to 500 yds. But, he was nothing special in the Marines....below average. But, I feel as far as against the general population of shooters, though, he was probably at least an average shot.
I generally agree. Like you said, he had qualified on significantly longer shots than what he had at Dealy Plaza's 180-265 ft shots.

Given all of the above; I find it unlikely Oswald fired 3 shots; accurately; cycled the bolt twice (2.3 seconds required each time according to the FBI), reacquired a moving target twice, looking thru a "tunnel" (the 18mm FOV scope) under pressure.
Here is a link to the House Select Committee on Assassinations's report, where they cite that FBI data.
https://www.archives.gov/research/jfk/select-committee-report/part-4.htmlThe FBI findings were [italics to not confuse your quotes from their quotes]: "
First, there was a test conducted by the FBI in 1964, using Oswald's rifle, which was a bolt-action rifle manufactured by Mannlicher-Carcano. The results showed that this rifle could not be aimed and fired using the telescopic sights in less than 2.25-2.3 seconds.2 Second, two committee staff members conducted a preliminary test in September, using a Mannlicher-Carcano similar to Oswald's. The results of this test showed that, using the open iron sights, the fastest that the rifle could be fired was somewhere between 1.65 and 1.75 seconds.3"Do you feel their estimate of a half second more to acquire the target in the scope is about right?
I've seen some examples of the set up, and everything you said about the scope and the field of view are dead on. It also wasn't like it was a fancy Schmidt & Bender scope on there.

I believe it much more likely he didn't use the scope at all; and fired using the iron sights. He was used to iron sights; had trained with them. It would be much easier to reacquire a target using iron sights:
Scope Issues Outweigh Benefits: The scope's misalignment, poor quality, and side-mount configuration likely made it a liability rather than an asset. At 60-88 yards, 4x magnification offers minimal advantage over iron sights, and the narrow FOV and awkward positioning could have slowed Oswald downcrucial in a short shooting window. FBI tests showed the rifle was accurate with iron sights at similar ranges.Oswald's Comfort Zone: His Marine training with iron sights at longer ranges (200-500 yards) suggests he could handle 88 yards effortlessly with the Carcano's sights. His lack of scope experience reinforces this preference, as adapting to a new system under pressure seems unlikely for a marginal shooter (191 in 1959).Practicality in the Moment: For three shots, including a miss and two hits, iron sights line up with the need for speed and simplicity. The headshot's precision could result from a steady aim over familiar sights, not a misaligned scope requiring guesswork.
Absent this explanation; I don't think there is any way Oswald fired 3 shots (2 accurately) in that timeframe, while cycling the bolt, using that scope to re-acquire the target each time.
Now, I think your conclusion based on your expertise and the FBI findings is correct in part. He absolutely could have used the iron sights the way the rifle was set up. And the FBI found that he could cycle the gun, acquire the target and fire with the Iron sights in 1.65-175 seconds. So without you reading the FBI report, your expertise and their expertise comes to the same conclusion. He had plenty of training and had the ability and time to cycle the gun, acquire the target and fire on target using iron sights, and not using the scope.
Your reasoning for him using the iron sights instead of the scope makes a lot of sense. And because his rifle was set up to be able to use either, he could have done either one. Like you pointed out, he was well trained on the iron sights. I know that even now, many people prefer iron sights. John "Shrek" McPhee preaches to use iron sights over a red dot on your every day carry and that is what he does.
With the FBI's time of 1.75s to cycle, reacquire, and fire, do you think he could have done it with the iron sights? He had 6 to 8 (or 11-13 if the first shot was before Zapruder turned on the camera) seconds to cycle and fire two more shots.
Again, thanks again for sharing your expertise with everyone!
