As referenced in other posts, the number of shots fired appears to be higher than 10, from the wounds [3 - 4 for the President, 2 - 3 for Connally], photos, physical evidence and eye witness accounts [2 furrows on the ground, the strike on the sidewalk, the strike on the cement near the manhole cover, the bullet implanted in the windshield chrome, the strike to the pavement on Elm, the strike to the curb which sent debris into the face of bystander James Tague].
James Tague's testimony was the most significant in contesting the Warren Commision's desire for a lone nut assassin firing 3 shots from the rear, in the 6th floor window of the Dallas School Book Depository.
I'm seeking AJ Weberman's consent to use the actual quote from Hemming [see Nodule 17, http://www.ajweberman.com/nodules/nodule17.htm], on his website, but the essence of one of his interviews is as follows:
The first shot was a plant. The bullet used was 'planted' in the soft tissue of Kennedy's back intentionally. A low powered sabot was used.
"Sabot-type slug ammo designs all utilize some type of relatively soft non-metallic sleeve material (usually polymer) that surrounds a smaller diameter bullet projectile. Bullet configurations and sabot designs vary widely by manufacturers and their types of loads, but all sabot ammo is based on the principle that the bullet "sheds" the enclosing sabot in flight (through wind resistance or the centrifugal force of spin imparted by rifling) or on impact."

If we credit the use of sabots, fired in parallel with the use of a silencer from all but the 6th floor window [had to be noisy], and the Grassy Knoll shooter [don't know why a silencer would not have been employed], then you could theorize that some of the 'marks' and the the impact to the curb which struck James Tague was the result of the casing, travelling at a high speed, but potentially a separate, or angled trajectory, than the actual delivered payload.
Hemmings makes this claim for the reason why the sidewalk was struck.
This could explain the large number of strikes, weighed against the number of wounds. The furrows in the grass and the curb where James Tague was standing were directly across from the Knoll [Headshot sabot fragments].
The Elm street hit to the pavement, which was dismissed as a miss, and sounded like a 'backfire' - no pun intended, could have been the result of the sabot fragment. I believe I've read that this conflicts with the impact demonstrated in the Zapruder film?
All pure conjecture, but it would go a long way to resolve some of the outstanding issues in terms of the actual number of bullets fired, and could also be used to determine the trajectory, if an expert could determine the percentage of variation on distance and velocity from center, based upon distance and power.
