My New Combustion

[cannon freak]

I have finally got most of my supplies for my large dual chambered combustion (Approximately 1050CI).

I was wondering, do you think i should go with a 3" barrel or a 2" barrel.
It will be capable of both but I can only pay for one at the moment.

The results that I am looking for are penetration power and destruction.

I know a 3" barrel could shoot larger things and cause more destruction but a 2" barrel could be more penetrating.

I just can't make up my mind, any help?

Oh ya I almost forgot, how could I hook up a large propane tank to my gun, my gun isn't very portable to begin with so I want to go with a large propane tank to reduce the cost of propane.

Also because of the type of fitting I had to buy in place of the T, the gun is now capable of triple combustion chambers instead of just 2 but for now an end cap will be in place of the third chamber, just for cost reasons but soon it will have a third.

2", just because it's been my standard for so long, then i switched to 1.25

The skinier your barrel is the more power you get.

I guess I will go for the 2" barrel then.

As for the large propane tank though, how would I go about hooking it into a injection system, I have no clue on the type of fittings required or anything, I do know how to make the injection system just not how to attach it to the large tank, so any insight would be very helpful.

Why don't you go for something inbetween. Ohhh, say, 2-1/2"? 8)

A water-injected tennis ball will definitely pack a punch.

I have no clue where to get 2-1/2" pipe though.

Search, not everything inlife is so e-z. look at canons that have propane injection systems and figure it out.

[cannon freak]

No the injection system isn't the problem its how to attach it to a large propane tank, you know the ones you use for a BBQ.

[mark.f]

Ahhh. You could probably find adapters for it somewhere, (Mr. Heater, Home Depot, etc.).

2-1/2" pipe can be purchased off McMaster-Carr, along with fittings to get it to 2" or 3" threads.
