40 max shell, 40max nerf shells “the stamppot shells”

IF YOU REMIX THIS, PLEASE LET ME KNOW, legally I can't oblige you to. But I would love to know what you make so I can add a list of remixes to the post!

The 40max shells are super popular, but strangely enough lack a large amount of community files. So here is a collection for you! The Stamppot shell list will increase with time so expect more crazy shells!

Last updated

I DO TAKE REQUEST FOR CUSTOM SHELLS SO PLACE A IDEA IN THE REACTIONS OR DM ME THEM.

This was made possible by:

Frozenfade (A beta tester)

FlipFlopFoamFactory (His awesome ideas for upcoming shells)

Gressimja (The name Stamppot shell was their idea, https://en.wikipedia.org/wiki/Hutspot for more info on the name )

And many more people who had great ideas and supported this project.
