blow pipes?

[Luci_ferson]

Ive actuall built one and used one a few summers ago.
and I know it wasnt really a good effort at building one ( bit of steel thin tubular pipe bound in a rope)
we did study the dimensions and principles of them.
the result was .
after a hell of a lot of practice I could hit a plate about the size of a light switch from about 8 metres but not with enough force to actually be of any use without the use of poisons (unadvisable).
However my friend who is about 5ft and roughly 14 stone instantly picked it up and fired a piece of plasticine through it with enough force to leave me with a large bruise on my calf that lasted about 2 months.
this was from about 6 metres away.
Id say blow guns for defence probably isnt the best idea,
theres many air rifles that can be easily bouught and are within legal requirements to own.
blowguns may be fun to play with and maybe practice with, but if you feal you need something for defence, Id go for the simplest option.
besides dont forget the trusty catapult. fast to reload and easy to master with practice.
it also has nothing to do with how big your lungs are.

why is it whenever i type something it comes out sounding nothing like i meant.

my point was.

try a good catapult with the sights on, a competition pro.
easier to master and can do a lot more damage when used with ballbearings
