Since it is an Archipelago that is surrounded by water. The Bad guys get most of their Armaments from the Philippine Military in an " Agaw Armas" program ( Steal one's arm). Going with a wildcat round will make it more difficult for the hostiles to use captured arms against the population and the government. Controlling the source of ammo is a good way of slowing down the rebels. A lot of military and police are killed so that their weapons can be stolen and used for many criminal activities.
How long do you think that advantage will last?
I foresee a quickly emerging black market for the wildcat round, and potentially a high price for stolen/pilfered ammunition. It wouldn't be much for one corrupt (or planted) shipping/security agent to divert a few pallets of the wildcat ammo into the wrong hands.
And think of it from this angle; several stolen dies for printing US currency made it into the middle east where several tens and potentially hundreds of millions of US dollars were printed on likewise pilfered authentic paper and using high-quality knockoff inks. If people are going to that extent to counterfeit US currency, the obstacle of wildcat ammunition is, in my humble opinion, a walk in the park.
Then again, I could be wrong as I do not know the conditions on the ground. I am just pessimistic about the likelihood of the desired outcome, given the information provided.
