okay expect some pictures SOON, just need to tell my parents a story so i can post some damage pics. Due to the dark covers of the magazines, i will remove them so you can see the enter and exit holes. It might be hard because there are holes from different pressure shots. Look for the middle hole. I will also post a picture of my gun, i know the chamber has wierd proportions and im going to up grade it soon(i also shortend it). Any suggestions for displaying the carnage?

damage to a block of plywood.  I used a pellet like the one on the left, it went in about 4 mm.   The one on the right is the one i used on the magazines, MUCH BETTER PENETRATION.

edited for double posting! 3 minutes apart!!!

SO it grabs attention




Sorry for double posting but....IM NOT LYING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!I did the best i could with the pictures it was taken with a phone camera. Ill addd some more shots at wood with bbs, pellets and darts next year, my 70 years old grandparents are comin over for christmass. I also found out you guys were right about the gage. It was shot at closely to 80 psi, i got a new one. I just thought that my updates on the gun wouldn't have changed the volume of noise, water vapour damage etc. Its MUCH more powerfull than last time.

This isn't to flame you, but rather educate you on forum policy.

1) Don’t create a separate topic for attention. This should be placed in the topic you originally posted with your cannon. It will bring your topic back up to the top. That should create enough attention by itself. People such as myself who did not see your first post will look at this in confusion.

2) Watch your double post. It's good you acknowledged it, but if you knew what you were doing was wrong then why do it....? :x

Next time simply edit your original post with the info! Don’t keep posting so people will look. If we want to look then we will.

Frankly, you’re bumping! :evil:

And how do we know that you didnt shoot the 5 magazines one by one?
Sorry dude
But we will need a vid of you doing it again to prove this.
You can do this again cant you? I mean, a lucky shot, okay; but a lucky shot that does 500% of the normal damage?! No way.

DAM! this is getting really anoying listen please - THE MAGAZINES I SHOT AGAINST ARE REALLY WEAK. WHEN I SHOT AGAINST A COSMETICS MAGAZINES IT EMBEDED IT'S SELF IN IT(198 pages in). I will do it again later. NEXT IM GOING TO DO A MOVIE, BUT DONT EXPECT IT RIGHT AWAY. My grandparents will be over and they wont want to hear or see me shoot guns! okay gah!!!! How many pages in a flimsy sh@tty quailty magazine can your guns shoot into? As i said, with "The Week" magazines it can go roughly in 300 pages. With a fixed gage the shots are done at 80 psi. At 180psi( I can go to 240 on my bike pump) I can shppt through 12 layers of cardboard with the same pellet. After i post a movie will you believe me? - SHOOT ME GOD, PLEASE! *red dot appears on forehead*

Fair enough man, they all don't believe you but I do.


@Xxplosive42o, your quote says....
" Forget about all the reasons why something may not work. You only need to find one good reason why it will. "


I think that this is most appropriate in this situation.

I mean come on im even telling you what magazines i shot against, so you could try! I told you there was a problem with the gage that i just fixed. I didn't realize it because the shot i did seemed different from the ones from my last gun.

How is 12 layers of cardboard extreme penetration ?
A spring loaded ballvalve canon with the right projectile could puncture 3mm steel plate at 240psi probably even 180.

But I do agree this whole I'M NOT LYING !!!!!!!!!(...)!!!! and double posting will probably get people frustrated quite quickly.

no people thought a pellet shot through 5 magazines, 3 layers of cardboard and ricocheting of a cosmetics magazine is unreal.

Its very unreal at 18 psi you stated in your last thread.

thank you, I have finished making a clay mould. Is calibers are:

-6mm roundball

-.35 roundball

-.64 roundball

All of these will be shot with a VERY fast opening valve at 300 psi. The metals i will try to use are lead or aluminium. Im also going to buy bronze rods for my 6mm barrel, dril holes in the backs and file a rounded, flat or pointed tip.

Also at the point of 18 psi not being believable, my gage said it but if sorted things out.( i tested it in cold weather) I just didn't think the pressure was higher because my last gun was much more powerfull, but lacking on the cosmetics. And for a power comparason, 5 of the magazines I shot against is about equivelent to embedding the pellet 3/4 into a plywood block.


Another thought, compared to a human layer of muscle, skin tissue how dense is a block of fresh clay? How dense is a straw archery backstop? Would tests be compareable?
