you still haven't answered my question, who an which is the lady in orange you are talking of in your thread here

As far as tumbling, that would depend on the rifling of the barrel. Sniper rifles are designed with rifling that would preclude tumbling, since this would disrupt the accuracy of the shot.
Hope this helps. Just my $.02

Rifling in the barrel contributes to stability in flight and don't have anything to do with creating a tumbling motion in flight.
A bullet which is fully enclosed in a metal jacket, as are virtually all military rifle bullets today, will start to turn around a lateral axis at some distance after entering the body. Once it starts to turn, the rate of turning increases rapidly; the angle of incidence reaches 90 degrees and the bullet continues turning until it is travelling nearly tail first. After that, it can partly turn several more times before entering the last phase, when it will again be travelling tail first. Depending on its construction, a full-metal-jacketed bullet can deform or break up because of the stresses placed on it during turning, but deformation or break-up of a full-metal-jacketed bullet is a by-product of turning and not an independent process, although, once it happens, the deformation or break-up adds to the wounding effect because of the increase in the surface area of bullet material pressing against the tissues.[20]
US M193 5.56x45mm - This bullet is fired from the US armed forces' first-generation smaller-calibre rifle, the M16A1. The large permanent cavity it produces, shown in the wound profile (Fig. 4), was observed by surgeons who served in Vietnam, but the tissue disruption mechanism responsible was not clear until the importance of bullet fragmentation as a cause of tissue disruption was worked out and described. As shown on the wound profile, this full-metal-jacketed bullet travels point-forward in tissue for about 12cm after which it yaws to 90°, flattens, and breaks at the cannelure (groove around bullet midsection into which the cartridge neck is crimped). The bullet point flattens but remains in one piece, retaining about 60 per cent of the original bullet weight. The rear portion breaks into many fragments that penetrate up to 7cm radially from the bullet path. The temporary cavity stretch, its effect increased by perforation and weakening of the tissue by fragments, then causes a much enlarged permanent cavity by detaching tissue pieces. The degree of bullet fragmentation decreases with increased shooting distance (as striking velocity decreases), as shown in Fig. 5. At a shooting distance over about 100m the bullet breaks at the cannelure, forming two large fragments and, at over 200m, it no longer breaks, although it continues to flatten somewhat, until 400m. This consistent change in deformation/fragmentation pattern has an important forensic application. It can be used to estimate shooting distance if the bullet is recovered in the body and has penetrated only soft tissue.
NATO 7.62x 51mm (West German version) - The design standards for ammunition that can be called "NATO" ammunition do not specify bullet jacket material or jacket thickness. The construction of the West German 7.62 NATO bullet differs from the US 7.62 NATO round in that the jacket material is copper plated steel, whereas the US version is copper (or the so called gilding metal alloy, which is predominantly copper). The West German steel jacket is about 0.020in (0.6mm) thick near the cannelure and the US copper jacket is about 0.032in (0.8mm) thick at the same point. This design difference is responsible for a vast difference in performance in tissue. The German bullet, after travelling point-forward for only about 8cm, yaws and breaks at the cannelure. The flattened point section retains only about 66 percent of the bullet's weight, the remaining 45 per cent becomes fragments (Fig. 8). The wound profile can be described as an enlarged M16 profile (Fig. 3), with dimensions of the tissue disruption increased by 60 per cent (temporary cavity about 22cm diameter; permanent cavity about 11 cm diameter, penetration depth of the bullet point about 58cm).
The longer 5.56mm bullets (M866, SS109) need a higher rotational velocity to maintain stabilisation in air. FN claimed that this faster rotation also causes the SS109 to have a significantly longer path in tissue before marked yaw occurs, thus producing wounds of less severity. This is simply untrue (compare Fig. 6 with Fig. 6). Additional rotation beyond that needed to keep the bullet straight in air appears to have little or no effect on the projectile's behaviour in tissue. However, there is a situation concerning rotation rates whereby these longer 5.66mm bullets can cause increased wound severity. Shooting the SS109 or M865 bullet in the older M16A1 rifle barrel (they are not intended for use in this 7-in- 72in twist barrel, but in the newer M 16A2 1-in-7in twist) produces a bullet spin rate insufficient to stabilise the longer bullets. Such a bullet will yaw up to 70° in its path through air. Striking at this high yaw angle (essentially travelling sideways), these bullets break on contact and the marked fragmentation, acting in synergy with the temporary cavity stretch, causes a large (over 15cm) stellate wound with the loss of considerable tissue (Fackler, M.L., unpublished data, 1988).

In my Kalishnakov I use 7.62 NATO. It's 148 grain MV of 2750fps. And you should see it rip up a car. I don't use FMJ rounds just the standard. I can also use the 5.52. Those rounds are interchangable with M-16s and most other weapons used in the world.
Wait now I'm confused. what were we discussing? What was JFK shot with again?

Speaking of the Zapruder film, did you know that Zapruder said he started filming as they entered the street. It is rather strange that the film cuts to the limo well after it turned into the street.
Wrong. That 40 years of research did not serve you too well Mayet. Look at frame #1 from the Z film:
It is as Zaprueder said it was, he starts filming as the motorcycles in front of the limo enter the street. You can't even see the limo yet!
You already know who I am talking about. I answered your question. You posted a picture of her at the end of page 2. Not too many people wearing orange that day.
Mayet...the quality of that picture is so horrible I can't tell who or what anything in the picture is....In fact, the figure closest to the camera looks like an astronaut with his/her helmet on!

It wasn't Jean Hill and probably not Beverly Oliver either.
No I am not wrong, you misread and misquoted me again. As I stated the film cuts to the limo well after the limo has turned into the street.
So if you are speaking of the lady in the red coat above, I do apologise but the lady is already named, her name is in fact Jean Hill and she is known as the woman in red,
I didn't misread or misquote you Mayet. You are WRONG. The film begins with the motorcycles entering the street ahead of the limo (which can't be seen yet in frame #1 of the Z film). I already posted a picture of frame #1. Do I need to do it again? You were wrong. Are you incapable of ever admitting you are wrong?
No I am not wrong, you misread and misquoted me again. As I stated the film cuts to the limo well after the limo has turned into the street.
Abraham Zapruder told CBS News that he began filming as soon as the President's limousine turned onto Elm Street from Houston Street, as one with the limousine already on Elm Street at Z133. On the day after the assassination, Dan Rather of CBS News watched what was quite possibly an earlier version of the film. Rather reported that in the film he watched that day the limousine "made a turn, a left turn, off Houston Street onto Elm Street." Again, no such event is now seen in the film. In the current film there is a long gap between the earlier motorcycles and the limousine's first appearance at Z133
I will depart for a moment and come back and edit in a frame of the Z film to show you who I mean, even though you already posted a frame from the same film and of the same woman in ORANGE!
She is well known by Serious researchers by the red coat she is wearing as the woman in red.
If you have something to say, come out and say it. Don't play games.
Do something anything with your serious research to show us that Green Man wasnt made invisible,distracted from and ignored for 40 years and maybe someone anyone will see your previous posts for something more than they are.
