			welcome to spud file 
oh and try remember to post in the right section next time 
i find a simple breech is just get a bit of pipe slightly larger than your barrel and drill a hole through both the bit of pipe and your barrel.
now to use just rotate the holes until they line up and u put your ammo in then rotate back to seal up. remember this design isn't completely air tight but a bit of duct tape on the outside of your barrel will help. heres a pic

			that is a good idea jssizzle, if you do that with a meatal ball valve be sure to get all the shavings out, cause i am pretty sure they have O rings inside and you don't want to wreck thous.
            
			
									
						
			trying to decide on a new project, probably something small.

			You could cut into the pipe big enough for ammo to fit in the adapt a screw on bottom and get the threaded pipe to slide in and screw on. This one is air tight and its not that much of a hassel to reload with some speed.
