Thats what i was thinking,and if i had a gun licence to buy the pellets id just by a mini pistol insted,just an update its actually a 4mm bore to be precise..sorry about that

Ball bearings are my only hope :roll: :x

I can get 5mm ones at anaconda (sporting outlet in penrith) 40 for 7 bucks.
Its just a shame i took a gamble on the size with out having my barrel with me and wasted 7 bucks :cry: oh well :!:

If I had a firearms licence,this hobby probably would of lost it's wow factor a long time ago.I think it's actualy what drives us to make small bore high velocity pneumatics,the fact that we don't have access to them.Unless you want to spend $800 a year on a licence,safes,police checks and then the price of the firearms ontop.

ok then. i have my firearms licence and didnt even think about it... i could post you some to try 8) . as for the pistol, i'd probably alredy have an actual pistol if it weren't for the crazy laws regarding them :? :evil:
EDIT; i still like shooting actual firearms, but you cant really make them yourself, which is the appeal for me... as well as being able to launch large objects :D

@rna_duealers
same here... if it wasn't so difficult to get a licence I wouldn't even bother to build a small bore gun


lol 7$ for 40 BBs ? I can buy 1k 6mm steel BBs for 150PLN... that's roughly 50USD

no offence dude but if this so called sports store was selling air rile pellets,im pretty sure it would be illigel and it wouldnt be in full view to the public,,correct me if im wrong but the only place u can buy ammunition is at a gun shop!

could you possibly inform me on as to what shop you buy your pellets from?

@poland spud
you laught at $7 for 40 but im yet to find a better deal in australia without going to enginering stores or online , i cant believe how hard it is for me to find the right size bearing, and you think thats laughable i recently went to an antiques and firearms show held at my local town, ive never been to an arms festival,i thort they only existed in america and they where selling sling shot ammo (x20 10mm steel balls) for $12 and you thort id been ripped off :roll: ,hey i nearly brought them :?

Australia has this thing about censoring or changing the law everytime a couple of people do the wrong thing,which pisses me off :evil:
i just hope fellow australians dont go throwing ball bearings around before they ban them, i need a small stockpile :D

@sandman i brought one today it cost me $70 which is a farken rip off

Unread postAuthor: FORE!!!! » Tue Sep 08, 2009 11:17 pm

just a bit of an update i decided to mount my mini coax to the underside of my slightly larger coax,lol

ive also built a mini push button to depress the shrader, made from a chrome valve cap,spring and a brass nut/bolt

now its double the fun :D what do you think?

also a quick vid to show they actually work, i fire the main one first and then the small one second at 300psi
