Obviously? That is not what the material states. What is stated is that a new, more efficient round was developed, two actually, and that they delivered the contents of the canister more efficiently down range.
I have a few questions for you as you are still progressing along the path of an illogical proof, ie, you're trying to prove what canister does not do instead of what it does, or did, do.
First, what do you think the round did after firing and while it traveled down the bore?
Second, when were the contents of the canister discharged?
Third, at what point did the cone of the canister balls form in the ballistic trajectory of the round?
