I ask that because when one projectile leaves the barrel, all pressure is quickly vented, and the other projectile lacks pressure, causing one projectile to go faster then the other.

Could we get a more detailed pic of your breech?


yes, ive tried jamming in two carrots before- usually only one actually leaves the barrel, probably because of different static frictions. things like paintballs or marble, however, are fine, the veolicity difference is negligeble. But, overall two barrels are better tthan one :wink: .

more pics to come i promise.

Hmm interesting.
Was that one carrot halfway up the barrel or still at the beginning?
How far was it?

Psycix- the carrot did not budge.
I went out today to do some damage to those watermelons. Unfortunately, my friend deleted most of the pics. Marbles went clean through, leaving an entry and exit wound. The bbs would go about 1/2 way through.

Damn..Nice rack! :D

Nice double barrel.Not many have been built.
The inability two fire both barrels seperately is no problem.The thing makes up for it in coolness.

Nice way to improve on the aging modded sprinkler -" rifle" design

I remember when you were just a little spudder koolaidman. lol, you have grown to heights i would never have imagined. I'm proud of you.

btw, awesome gun rack/guns. mind posting me links to them (i was away from the forums and missed out on the topics about them).

Thanks, again, great work

sweet looking gun there, the stock really caught my attention, looks like a very ergonomic gun.

However i am not so impressed by the use of the same diameter of pipe for the chamber and barrel, especially when there are 2 barrels, and the chamber has bends in it, this looks intense, however i suspect that it has relatively low power. I would have made the chamber 1" or even 1 1/2, then theres more chamber volume, more room for air to flow through the bends and a better ratio for the barrels. it also would be better to grip.
