Custom Load Development & Testing Service for Unique/Large Bore Firearms.
The comment 'Can you make a slug for it and test it against soft targets like fruit and harder ones, say, metal plating softer than AR500?' directly asks for specialized ammunition and performance data for an uncommon firearm (punt gun). This suggests there might be a niche market for a service that develops, produces, and tests custom ammunition for unique or large-bore firearms. Such a service would offer enthusiasts safe, optimized ammo and valuable performance insights where commercial options are limited.
Expected benefit: Access to tailored, tested ammunition for non-standard firearms, enhancing their usability and the owner's knowledge.

Maybe you can find a nice mountain or something as a backstop, not sure what else would work lol

Can you make a slug load for it too and test it vs soft targets (like fruit) and hard targets (metal plating softer than AR500)?

I have 5000 grain round ball I'll be testing out. I need to find a better place to shoot them. Shot doesn't go too far, but I don't want to take a chance with the ball.
