Is this a shot test

[Ian Patrick]

The front armour plate on my LP2A carrier and some other LP2/2A carriers I've seen have test marks that appear to have been caused by a bullet-like impact.

These appear to be reasonably consistently located in the same spot(s) on various different carriers which would seem to indicate that the test was undertaken either after the carrier was assembled or at least when the front armour plate had been cut to shape. Logically this would indicate the testing was done at the carrier assembly plant rather than the steel manufacturing plant.

These marks have not been caused by a ball striking the plate but appear to be from a small diameter sharp object hitting the plate with some force.

Any ideas?
