Not really, on the manhole cover shot, or on the shot that struck the asphalt behind the limo. Those are only witness statements. The curb shot strike by Tague was found to contain lead, but not copper. That may indicate, as you say, sone lead squished out of the Z-313 shot and struck the curb by Tague, and not a whole copper-jacketed bullet. That seem little far-fetched, but anything is possible.
One scenario is LHO was shooting to miss, while others shot for real.
There are oodles and gobs of KGB*-endorsed scenarios which, by definition, ultimately require beaucoup bad guys' to be involved, one way or another, in the planning, the "patsy-ing," the shooting, the planting of false evidence, the getting-away, the altering of photos, films, and x-rays, and the all-important (and ongoing!!!) cover up.
LOL!
*Today's SVR and FSB
A guy calling himself Herb Huskr at the "JFK Truth Be Told" FB page has shown that, given the fact that a bullet fragments from the fatal head shot dented the limo's chrome strip and cracked its windshield from the inside (leaving lead residue on the inside surface), if another largish fragment from the head shot had a slightly higher trajectory that the chrome-strip-denting fragment, it could have made it all the way to the curb, chipped it, and caused a bit of it to nick Tague's cheek.
I posted his article on another thread.
Have you read it, yet?
This is what Huskr posted at that other forum about a year ago:
There is some active discussion on another forum where I’m not a member about James Tague being hit, a curb mark, and what happened there.
This post is about some modeling and simulation results made awhile back evaluating a possibility to explain that Tague incident. I’ve not routinely discussed these details before because there is a back story that suggests that the modeling indicated how wrong I may have been with my initial gut feeling, and who wants to embarrass themselves by admitting they may have been misled by an erroneous gut-feeling bias.
The modeling was done a few of years back to try and prove this initial assumption:
A missing fragment from the z313 head shot could not have made it to Tague and created a shallow curb divot sending mortar/sand shards up and out, with some striking Tague in the cheek while he was standing nearby.
The envisioned scenario (initial gut feeling scenario) looked something like the following:
A disfigured lead, or lead with residual copper, bullet fragment flying forward escaped the limo from the third shot, at maybe 400 ft/sec, continued on to strike the curb with a compressive strike from a mostly horizontal trajectory, hitting at a reduced velocity around 200 ft/sec or so. This possibility was expected to be proven untenable and therefore likely wouldn’t happen.
Results:
Embarrassingly enough, the modeling predicted I would be wrong on every single account!
A fragment could have made it to Tague
The initial exit velocity would be more than twice the 400 ft/sec I was thinking
The final velocity would be even less than half the 200 ft/sec I was thinking
The angle at striking would be opposite, nearly vertical, instead of more horizontal like I thought
The curb strike likely presented a shearing force rather than the head-on compression force I expected
Talk about being wrong!
A crude curb-strike simulation was subsequently conducted to look at this because the predictions seemed so unusual.
Overall, the modeling and simulation indicated the scenario looked to be a real possibility, with a limo exiting fragment able to reach the curb by Tague and cause a spray of surface mortar that could hit him.
It is still possible the model is not accurate enough, or the fresh mark was not related to a bullet at all, but the modeling came up with numbers that were largely predictive of observations that others subsequently measured on such fragments, like what Lucian Haag found for fragment exit velocities in his simulated skull test shots experiments, and Carcano fragment ballistic coefficients.
Two options for base case trajectories for the incident are depicted on the attached graphs.
Based on the modeling and simulation, I now favor that a rogue fragment from the head shot caused the Tague incident.
I will try to make a link to a summary with more details for those interested in ballistics, etc.
