Heavy Hitter Shotgun Slugs with Incendiary/Exploding Mod

We test another batch of the Heavy Hitter shotguns slugs. These 1.5oz slugs are massive. They have a large internal cavity which allows you to fill them full of “stuff” for a dramatic incendiary effect, while staying legal. (the amount of powder small)
We wanted to see if adding a nitro card would help solve a previous issue.
These slugs are still in the development stage so a few bugs are still being resolved. We will also test some from a full rifled barrel in the next phase of testing.
