nope, I'm leaving it muzzle loaded. I still need to fix the barrel because it doesn't point straight which makes the scope useless =/. And bravootome, where might I find a dump of unwanted fridges lol...

people use to throw away old fridge ....i even found a functional large fridge with 2 compressors . GO to the recycling area in your town. It's impossible not to find at least 1 fridge there.

This may be a valid time to remind people that releasing CFCs into the atmosphere is governed by international treaty.
Not all fridges do use CFCs, but getting caught cutting into one that does (and there's often no easy way to tell) can get you in serious trouble.

(Also, regardless of whether you get caught, it's morally questionable).

yeah iv got a mate of mine that works as a fridgy , they use a very complicated method for reclaiming cfc's and other refrigerants, they call it rag recovery. as in just crack open the pipe some more and put a rag on it.

nope, I'm leaving it muzzle loaded

boo ! lets see a mag fed design for this little plinker.
im sure you will find that your scope will sight in once you encase the whole thing in a nice wood body to keep it ridgid

Utter bollocks. There's specialised machinery for this type of thing, given how much damage it can do to the environment.

Either your mate is having you on, or he needs a visit from the authorities.

you may ask your father to talk for you ! :lol:
Yes it's that simple.]so uhh... how does that conversation go?

as about the "freon " gas ....and damages it makes to the atm.....
is is a high standard of recycling ..not used where i live . However the forests we cut are having a much larger impact over.
Just looking at news few day ago, and 70% of the forest in my country had been brougt by foreign people or companies . It is incredible to see how in 1 year mountains can be "unforested"
