Haha, that would be impressive if his made a dent. I wonder how he made his, it does seem interesting though considering its made mostly out of duct tape.

Say Larda penetrates an inch.
This guy gets 0 penetration.
Larda's projectile travelled at say..mach 2.
mach 2 times 0...
So this guy's ammo did NOT move at all.

Now he's done it:
Sticking a barrel to a nailer with duct tape.
The only creativity so far is in his calculations.
I'm getting pretty pissed at this guy...
So now he's more creative than I am...my air gun will own your air gun in no time, i will upload a video shooting with it soon. im not saying yours is not good, but mine is much more better. dont be upset we are here challenge each other by who is more creative thats all.

Arghhh, this person :cussing: He's just so.... srthy5ncyi8jjuy.
i just wanna challenge him to a duel, he can use his gun, i can use a Ruger MkIII. Ofcourse, his gun would be far superior...

Nope, i really think he thinks it's firing at 2000fps. This guy is making me very angry... I make have to even make a video of my firing through more pages than him then mine will be "the best in the world"

Never argue with a fool.
His mind is made up and you can't change it. He is still convinced he has 2K FPS at least. Only after he educates himself will he be able to change his own mind.
Someone ask him to model it in GGDT and post the results.

He'll respond that the program is not compatible with his 5 part barrel flux capacitor so only counting pages will tell the true tale.
That or a sodacan not moving.
An actual chrony will probably be disrupted by space being warped during a shot.
If I where to shoot through a zombie-pig completely I'd have a serious airgun.
Launch that same zombie-pig up into the treetops as you shoot through it is clearly a sign of a weak shot.
If I where a bouncer still...I'd invite him over to the club for a friendly and creative discussion...

Hahaha, we're winning! He just goes off-topic when i comment and replys with something rediculously stupid...
But this - Clever guy
That is a reasonable homemade pellet gun. I respect your construction efforts.
The only flaw I see is your calculation in the speed.
The kinetic energy for a .177 caliber 8 grain pellet at 300 fps is 1.60 ft-lbs.
This is what 10 pages corellates to.
To get 100 pages you would need 14.43 ft-lbs. This turns out to be 900 fps.
Just by tripling the 300 fps you will get the 100 page penetration.
The formula used is KE=1/2mv^2.
So please understand this formula to get the actual calculated speed.
Mouyad888-thanks for the comment, i probably made a mistake about the fps calculation but i did not mean to mislead people about it...
Ofcourse you meant to mislead people!

Bravo! You're battling with a retard on the internet.
Something that comes to mind...
"Don’t argue with idiots. They drag you down to their level and beat you with experience".
It did make for an interesting few minutes of reading though.
Feel free to continue with the entertainment.
