I’d delete the ‘g’ for pirate-speak…the more unintelligible strings of consonants there are, the closer you are to zombish.
As for the ammo…I’m honestly interested to know more about the cavity filler, even to see it tested. I’ve seen things as minute as a drop of superglue in an HP cavity get a JHP to perform very differently in test media. Manufactured or added to standard factory component bullet? (I added colored fillers to some Lapua CEPP to make “depleted uranium” 9mm years ago when I lent a hand to a small indie film production. Little did I know that DE 9mm would show back up again in the most recent Bond flick…)
The ammo-knerd in me wants to know.
Lastly, I try as best I can to be open-minded about fantasy worlds such as the zombie stuff…but .50BMG? C’mon, I’d rather see anti-zombie stuff in .22LR, 5.7x28mm, or other cartridges likely to be employed or desirable when Great Grandpa decides to come back for some long pork.
