Algodoo

1x2m casing, 1x3.5m catridge. just an attempt to standardize algodoo firearms(hovewer, you're not imposed to use them). i'm not sure if the frag grenade works on phun, due to old density bugEDIT: it works, but it's extremely weak. PROBLEM: when loaded onto algodoo it causes stuff in the ground to disappear if the scene has no killer planes.

fired and spring-detached with collision group B. barrel length and friction can(somewhat) determine the bullet speed.

EDIT: now increased pressure for(much) more power.
