Moving ammo/bomb at the back of the weapon/gun

Look at your first answer. It doesn’t even an answer to my question. I never said you don’t have more experience,you probably do but if you don’t answer properly, you are not helping. If you won’t help, there is no need for you to answer. Don’t just go to a question and underestimate people with your simple solutions(!). You also don’t know how much experience does that person have.

I am going to check this answer as solution but it does not solve my problem. Thank you very much again.
