Is there a way to conveinently fuel your chamber without taking the endcap off?

Alright, I would like it to be reusable and not a fruit that costs 3$ each.

well, obviosly potatoes. I've tried it and there great. But i hate shoving them down the barrel and i run out very quickly.

Is there a way to rifle a barrel at home without spending much money? (5$ max)?

Hey, I just made myself a spud gun with 1 1/2 diameter barrel. What is a good thing to shoot out of this? (Please don't reply with metal projectiles)

Thanx

Dave
