how i can have that power ? he uses 6-7 bars i use 8 bars and i can even penetrate Thin wood ?

what ammunition, he has some big slugs

How i can have the same power? He uses 6-7 bars and he can penetrate all that , i use 8 bars and i cant even penetrate thin wood. I use 8 mm barrel and 8 mm steel balls . My pilot is air compressor gun

its 0.7 metres long barrel 8 mm

Should have good power then, you could be losing pressure through the blow gun, normally pressure goes the other way to seal.

also how snug is the projectile in the barrel?

Your pilot volume looks huge. That doesn't help.

Agreed, try it like this and see if power improves:



Can the projectile roll down the barrel easily?

Do you have a system (like for example a magnet) to keep the projectile in the breech?

This tee is for bicycle pump , no i dont have magnet , Iuse toilet paper and ball

Yes , the bullet is going easily , but sometimes if i wrap bullet with toilet paper its hard to push bullet into barrel and air its not pushing him

Sounds like the projectile to barrel fit is good.

If you take off the barrel, pressurize, and try to fire, what happens? A loud pop or just a hiss out the pilot?

A little loud pop

With a proper pilot you should be good, I used a slide valve for my experiments and it popped very well.

If i will do that , how much my power will increase?

I can't quantify it exactly but the more pilot volume you have, the slower the valve will open and the less power you will get from your projectile.

Have anyone other ideas to increase power please?
