I don't need to google that, I already knew it, that's where I got my idea. Just don't know how good is it in reality.

I would put the rifling at the muzzle end of the barrel.

For the .22 I can do the same but the barrel is very expensive, so can a smooth bore pellet gun be accurate? Both guns will be very well machine made, so I want them to shot as good as they looks.


Medium weight diablo style pellets will fly well out a smoothbore barrel, after all that's what they were designed for. Don't forget that there's more to accuracy than just rifling though, trigger consistency, pressure consistency, valve consistency etc.

That´s what I´m studying now :) thanks Jack! Why the rifling in the end? That´s more difficult for me to instal :roll: maybe I should make both smooth bore...

When the projectile hits the rifling, it will be travelling faster, and therefore spin the projectile at higher RPM

Understood :)
AutoCAD vs SolidWorks witch one it´s better? I like Solidworks more because it allows animations.

It gets really complicated when you begin with complex designs....
