no i think its my lifting system that jam a bit... cause i delete a block that fix the link and the ammo together but i think the rectangle that does that is
a bit too far.. basicaly fiddeling the things. and i am lazy.. its working sometimes ok ahahha
make a shell and a bullet.. fix a block that will be delete lather on the bullet, attach a spring on it and increase the length and fix teh bullet to the case with an other block. to release the bullet, you use a block that will delete that block. you make a barrel that will delete the block so the spring and you have a gun
or check one of my guns for exemple, its easier to see than describe
