Has anyone tried this and could they confirm if it actually increases FPS. Wouldn't it also shorten the life of the piston because it would hit the wall of the cylinder harder? Also, if you cut it half way, then would cutting it only 1/4, leaving 3/4, increase the FPS just a little bit?

If you don't know what I'm talking about, watch this.

I wouldn't pay attention to that article. Based on experience, without hopup your gun won't go farther than about 100 feet. Also keep in mind that the article/calculator didn't take into account wind resistance, and that the gun doesn't maintain a constant velocity but rather decreases in velocity rapidly once it leaves the barrel.
