Gayle and Robin, Thank you.

Robert, One of those relating to this area? https://drive.google.com/file/d/0BwrExtVD005ON3labE1kdlYzcVk/view?usp=sharing chris

Ramon, Some other items. https://www.facebook.com/media/set/?set=a.469620866449396.1073741833.109813095763510&type=3 chris

Roy, A little backseat footage. https://drive.google.com/file/d/0BwrExtVD005OQUx6U25wRFp2QWc/view?usp=sharing Of course, cleaning up the scene prematurely might create more difficulties in figuring out exactly what happened. I recommend downloading the bottom link as opposed to just playing it, because of its size, it appears to have buffering problems. https://drive.google.com/file/d/0BwrExtVD005OdnQ4eHluV1ZhUjA/view?usp=sharing chris

Paul, I believe the frames Martin supplied are from this clip. https://drive.google.com/file/d/0BwrExtVD005OVm9jMWRSNmJhMU0/view?usp=sharing chris

Roy/James, One of the few times I've seen the seat in the raised position. chris

Roy, Jackie and Jack entering the limo at Love Field. https://drive.google.com/file/d/0BwrExtVD005OSUctamRYWTFZU0U/view?usp=sharing chris

Using JFK as the marker with the pedestal and yellow curb stripe as stationary items, the extant Zfilm shows the limo traveling approx 7.2ft from frames 301-313. 18.3/12 = 1.525 x 7.2 = 10.98ft per sec /1.47 = 7.47mph chris

James, I tend to agree with you. Throw in the convertible top support while viewing from the right side of the limo, and it creates a very difficult shot. chris

Doodling. I believe it's easier to imagine Jackie in the body position that Connally describes himself in, while being shot. West end. chris Connally.mov

Doodling.

Thank you Chris. Sorry to make you search for the info. I wrongly assumed that you had this information already. I just PM'd Pamela with my question. Tom Tom, We need the height from "street to the top of the back seat that you sit on". chris

Does the blue line intersecting the bullet hole and chalk mark represent the same location in both photos? chris

No. Not above the ground -- above the floor. The chalk mark height above the ground would by 3 feet 5 inches or 41" PLUS the height of the floor above the ground. I do NOT know the distance from the floor of the JFK limo to the ground.Tom Tom, What little I could find. http://educationforum.ipbhost.com/index.php?showtopic=13098 chris

This was 90 micron powder loaded into a frangible bullet? I expected small buckshot... Would this powder even appear on an X-ray taken by portable equipment manufactured prior to 1963??? Tom I would imagine it would, Tom, although there is no reason to assume that a lethal frangible bullet in 1963, when they were still in the developmental stage, would be made from the identical materials as these ultra-modern frangible bullets. Below are two views of Italian issue M37 "Magistri" 6.5x52mm Carcano frangible bullets, manufacture date likely in the 1930's, although collectors have M37 cartridges with headstamps dated as late as 1953: Before you all get excited, thinking we've found the bullets that killed JFK, I should explain that this type of frangible bullet was designed as a "safe" bullet for shooting in indoor and urban ranges. One of the properties I neglected to mention about all frangible bullets is that they will also disintegrate to powder when they impact something hard like concrete, steel or rock; meaning there is no danger from ricochet. This feature, plus their incomparable stopping power, is making frangible bullets very attractive to urban law enforcement agencies. The M37 Magistri frangible range bullet was a very odd bullet indeed. As seen in the top photo, the copper alloy bullet jacket was made in two pieces (soldered together I believe though I am not certain), plus there was often a deep groove at the cannelure, seen just above the mouth of the cartridge in the top photo. This tells me that, on impact and penetration, there was a good possibility the bullet jacket would quickly be in three pieces. Consider the potential of this information when considering all of the WC's evidence regarding bullet jacket material recovered from the head shot. What is even stranger is the internal construction of this bullet. Just inside the nose of this bullet is a tiny pellet made from lead or "maillechort" (copper/nickel alloy). Behind that, the middle section of the bullet is made from compressed lead powder, the fineness of which I have been unable to determine. Behind that, the base of the bullet jacket was filled with sand. The M37 frangible bullet weighed only 108 grains (sand being much less dense than lead), compared to the standard Carcano FMJ bullet at 162 grains. To keep the velocity of the M37 bullet the same as the FMJ bullet, the gunpowder charge in the cartridge was reduced. As can be seen in the lower photo, the nose of this bullet is not complete, and the lead/maillechort pellet can be seen through the small opening. I am not sure of the purpose of this opening but, I am told the pellet served to break up the bigger jacket on impact, and to fracture the bullet's core into dust. God only knows what effect would be obtained by shooting this bullet into a skull or lung but, I believe drilling a tiny hollow point into the open nose of the M37 Magistri bullet would give us something quite similar to the hollow point frangible bullets seen in Chris' video. Robert, I like the above idea. The bullet speed is still bothersome in terms of an explanation. Hard to believe they missed his head and hit his back instead. If professionals did this, why not a direct head shot? Ideas??? chris

Everyone's in bed, and I can't do these measurements accurately without assistance.The only measurement I can take is from the floor to where the chalk mark would be on me while seated (I'm 1" shorter than JFK) is 3' 5" above the floor. So I'd say 3.27" is too low... Tom Tom, So the height you assign the chalk mark would be approx 3ft 6inches = 3.5ft = 42 inches above the ground? Would 3.56ft = 42.78 inches be within range? chris

Tom, Yes. How about a back wound at 3.27ft above the pavement. If this photo represented JFK in the limo, would the chalk mark appear to be 3.27ft above the ground? Remember, the top of JFK's head was measured at 52.78 inches above the ground. chris

My sentiments too. Here is a link to the entire video if interested: The clip I posted was the most comparable to a carcano. imo

Chris, Actually he is drawing a simpler path than the official version. West is looking at him expecting the end result to be a hop-scotch variation. P.S. Since the WC were experts on tripods up on the 6th floor, Shaneyfelt felt right at home helping West with his theodolite.

Something to keep in mind.

http://forensicoutreach.com/the-falling-bullet-myths-legends-and-terminal-velocity/ Interesting analogy, just in terms of the speeds obtained from a free-falling bullet. SB_Pete's comment, ninth entry below article. I'm not insinuating the back wound was created this way.
