Confused..

[VoidSuicide]

As in use water to compare the volume of air in the barrel vs the volume of air in the cylinder?

[Felix]

I wouldnt do that, but you could try perhaps?

[VoidSuicide]

Idk. it was the best idea i had, and I wouldn't dream of doing it without both parts being out of the gun and away from everything that i wouldn't want wet.

[Felix]

Well weting the cylinder would make me doubtful. same with the barrel. Just for rusting or whatever.

What I read you should do is just drill a hole in the cylinder. Pi x radius(squared) x height will give you the volume of your barrel or you cylinder. so you just have to figure what the volume of your barrel is, then drill a hole where needed in your cylinder so that all the air after that hole=volume of barrel.

[VoidSuicide]

Math is murder on my brain. I'll need a simpler way then all that calculation.

[cripto]

how long is your barrel?

[VoidSuicide]

Right around 205 mm.

[cripto]

28.26mm(squared)x205mm= 5,793mm(cubed) so you need to know the height and length of you cylinder for this info to help at all.

I'll look into it this evening I guess. I'm almost afraid to take this gun apart.

So basically the air that is released from the hole dispates, and the air in the barrel replaces it?

Hold up, you guys are moving way to fast.

The water method could work, but math is easier and cleaner. As long as you've got a pencil, paper, and a calc, it's not hard math. It's also not as easy as simply matching up the numbers. In a perfect world, then yeah, that'd work, but, if you haven't found out by now, we aren't in a perfect world.

The ammo you use has a huge effect on how much you need to have your cylinder ported. BBs of different sizes have different amounts of air that passes by them as they are flying down the barrel. The larger the inner bore of the barrel, the more air you lose around the bb. Same thing with the weight, the heavier the bb, the longer it takes to fly through the barrel, and the more air that will leak past it. So it's not so simple as just matching the cylinder volume with the barrel volume. Generally, the cylinder needs to have 150% to 200% of the volume of the barrel.

And that's where it gets tricky, because you've got to start experimenting, and figuring out that perfect balance of air, bb, and barrel.

Oh, ok my bad. Sorry for any misleading info.

Wanna test your method on my rifle Kory?
