But if it needs to be rammed down it would create a better seal thereby needing more force to exit the barrel. Sure you could weight it or make a cannon ball but going out and buying more pipe to make it fit better? You could make a sabot.

But fair point. If it fits I spose

Hey
This kinda relates to this. I made a breech loader for my pneumatic and what i did was with an offcut from my barrel big enough to cover the hole nicely, i cut a line from top to bottom of the offcut to open it up, i then heated it up and wrapped it around the barrel to mold it to the shape of the outside of the barrell. Then with cable ties and a metal hose tie i strapped it onto the barrel, it formed a very nice seal over the hole.
Also when the pvc pipe was felxible to mold it was still cool enough to handle with your bare hands.
I just thought i was say this because it relates to the heatgun on pvc thing
