Amazing gun there dude. Great work! :D

What sort of speed are you getting with marbles? What size barrel are you using?

Really cool rifle. I really like the rifled barrel and the spot for the ramrod. A very nice touch.

Thanks guys.

3/4 polly barrel and not sure about the velocity might chrono it later.

I recon to rifling is way cool,it's basically it's own outstanding characteristic.

Well to tell you the truth,I'm not all that happy with it as I had to rush the build...Had to go see family which took away 3 days of my time to build so there would of been a few more features and a little cleaner but it's still non the less....

Ohh and follow the link bellow for rifling.

isnt rifling supposed to slow down the bullet a little bit? although its a nice gun..u should have built a piston and made it look like a rifle...although i like it..
4" piston valved cannon-half done..( i spilt my cement...)

Hybrid- 75% done. need to build propane holder and drill/tap sparkplug hole..

Great gun there. Two thumbs up on the rifling. I agree with Spudthug though. Great job on the gun so far, and it also has so much pottential by adding a piston valve later on. Don't forget to post the results of the chrony when u get them.

RNA, I don't know if it is the picture distortion or not but it looks like the rifling straightens out a little towards the muzzle.If so that could be an issue at long ranges.Any ways nice gun, I like the aluminium.

I don't think so. If anything, by putting spin on the object, it would travel faster and farther.

Oh and by the way...
