JFK Assassination Plus General Discussion And Debate / Re: Applying Logic and Critical Thinking to the JFK Assassination
« Last post by John Corbett on Yesterday at 02:14:56 PM »I figured out why my sources on the Marine Corps rifle qualification standards differed somewhat in the allotted times for the slow-fire and rapid-fire phases: the source I'd been using was for the 1943-1955 standards, whereas the source I found last week includes the 1943-1955 standards and the 1955-1968 standards. Oswald was in the Marine Corps from October 1956 to September 1959.
The 1955-1968 rifle qualification standards prove it is untenable to cite Oswald's Marine Corps rifle scores as evidence he could have performed the alleged shooting feat.
Oswald's performance on 11/22/1963 proved he was capable of making the shots that killed JFK because the evidence he did that is overwhelming. The burden of proof is on the CTs to provide the evidence that he was NOT capable of making he shots.

First off, we must keep in mind that when firing for qualification in the Marines, Oswald was using a superb semi-automatic rifle, either the M1 or the M14 (the M14 replaced the M1 in 1957, but the M1 was still often used for rifle practice and qualification). Thus, whether using the M1 or the M14, he had no bolt to manually operate--he just had to aim and squeeze the trigger. This is a huge difference compared to firing a bolt-action rifle where you have to manually operate the bolt for each shot.
A semi-auto like the M1 does automate the chambering of each round after the clip is inserted, but once the round is in the chamber, the fundamentals for making an accurate shot are pretty much the same. Both rifles have significant recoil which will require the shooter to reacquire the target and put the sight on the intended target. A bolt action rifle has the added step of manually operating the bolt to eject the spent round and chamber the next round in the clip.

Second, when firing for qualification, Oswald was firing at stationary targets, targets that he had practiced against several times beforehand.
A slow moving target moving almost directly away from the shooter is almost stationary in that there is very little movement in relation to the line of fire. That would have been true for Oswald's second and third shots but not for his first which is why that shot was by far the most difficult.

Third, and this is a crucial point, to score a hit at 200 and 300 yards, Oswald had to hit a black circle on the target sheet that was 10 inches in diameter (10 inches wide and 10 inches tall), nearly twice as wide and 22% taller than the average male head. The average male head is 5.5-6.0 inches wide and 7.8 inches tall (from bottom of chin to top of head). To score a hit at 500 yards, Oswald had to hit a black circle that was 20 inches in diameter, more than triple the width and more than double the height of the average male head.
The effect of firing at greater ranges effectively makes the target smaller. I guess during your critical thinking you failed to take that into account.

Fourth, even in the two "rapid-fire" phases, Oswald had 5 seconds to fire each shot. For the four slow-fire phases, he had 72 seconds (1.2 minutes) to fire each shot. Let's look at all the times for all the phases:
Stage One-Slow Fire
200 yards
12 minutes
10 rounds
Firing rate: 1.2 minutes per shot
Stage Two-Slow Fire
Stage Three-Slow Fire
300 yards
6 minutes
5 rounds
Firing rate: 1.2 minutes per shot
Stage Four-Slow Fire
500 yards
12 minutes
10 rounds
Firing rate: 1.2 minutes per shot
Stage Five-Rapid Fire
200 yards
50 seconds
10 rounds
Firing rate: 5.0 seconds per shot
Stage Six-Rapid Fire
300 yards
50 seconds
10 rounds
Firing rate: 5.0 seconds per shot
See: https://www.wwmcmillan.info/usmc_FirearmsQual.html.
Fifth, to qualify in the "sharpshooter" category, Oswald only had to achieve a score of 210 out of a possible 250, with each shot counting as 5 points. This means he could miss 8 of his 50 shots and still qualify as a "sharpshooter"--and, again, this was while using a semi-automatic rifle against 10-inch and 20-inch targets that he had practiced against several times beforehand.
Let me see if I can do the arithmetic without a calculator. Oswald had to hit 42 out of 50 shots to qualify. That's an 84% hit rate. When shooting at JFK, he hit his target 2 out or 3 times. That's a hit rate of 67%. Sounds like Oswald was a little sharper when shooting in the USMC, but let's cut him some slack. He was firing with a bolt action rifle.

Sixth, Oswald was always firing from a level position at Marine Corps rifle ranges, and never from an elevation, not to mention an elevation of 60 feet. Thus, he never had to worry about the high-low factor when firing from an elevation. It is doubtful he ever even heard of the high-low factor.
When firing from a level position or an elevated position, gravity starts to take effect as soon as the bullet leaves the barrel. The shorter the distance, the less the bullet will drop while in flight. Oswald's longest shot was 88 yards, so gravity had less effect on his shot.
Quote
Clearly, his Marine Corps rifle scores tell us little about his ability to use a bolt-action rifle from 60 feet up while firing through a half-open window in cramped conditions and to score 2 hits in 3 shots in a 14 x 4-inch area in no more than 11 seconds and to score his 2 hits in 5.6 seconds (since everyone agrees the alleged lone-gunman's first shot missed).
14 x 4 inch area? I didn't know JFK was a pinhead.
