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.

Are you noticing the effect from the 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...

thats a really cool barrel. do you think it would work on copper? thats a nice gun overall.
