a 60 cm 1" chamber would be big enough for and 80cm 3/4" barrel

80" Squared and 73" Squared respectivly

Hey mate, thats a good looking design you got there! You can get a bag of 100 marbles from shops like crazy clarks for dollars and cents for 2 bucks a bag. When it comes to ammo, you just can't beat em. I've got about 1200 marbles lying around my shed haha.
