lucky B****** i wish i lived 300m away from a beach... maybe you could try skimming a golfball or something (not sure how well it would work on wavy sea) and shooting over water could be useful for checking out range because you would see the splash, unless your cannon is so powerful it shoots stuff over the horizen 8)

Well I have a golf course right outside, so I do my primary range shooting there when it's closed, or deserted.

Makes it easy for calculating range because I find out what tree it lands next to and go on google earth and use the ruler.

If I shot into the ocean I would have no reference to measure it against in google earth.

you shoot over an inhabited area :shock: i would be concerned about the ammo like landing on someone or hitting tem in the back of the neck and killing them or something... i spuppose you could shout "heads" before shooting :lol:

Well this is my main shooting range for the golf course shotting from my house. The yellow area is the safe zone where I can see what i'm shooting at, the furtherest recorded distance is just under 390m without the sprinkler valve.

So i've maxed out the distance at 400m until I get some solid figures witht the sprinkler valve, because at 420m i'm going to be hitting roads and houses :oops:

I've never seen 1/4" PVC fittings, but I have seen 1/4" steel tees (steel's always threaded) Did you mean a 1 1/4" tee?
As to your question about a blowgun piloting the valve, you can try, but you'll have to have a really tight piston. I wasn't able to pilot a 1" hot glue piston with a heavily modded blowgun, but pepto bismol bottles are a pretty good fit, and I'm don't have the best record of sucess with piston valves, (How many tee's did I ruin? :oops: ) so I'm sure you could do it. You'll probably have to mod it though.

@MrCrowley: It's kind of funny that the SGA is louder than the SCTBDC. No one outside of my closest neighbours have ever heard it. Must be something to do with the efficiency; the pressure drop on the SCTBDC is 430 psi, so only 40 psi is left at the barrel tip. What's the pressure drop on the SGA?

unfortunatly google earth has died on me but i will use multi map to try and explain... my village is the big one bottom left and i would be shooting roughly NE towards the village at the top in the middle and i would be shooting from the bottom left corner of the field NE right by my village :)

yeah i have a super awesome 3/4" qev cannon that can shoot a 4g paintball 2000 yards :D lol not really i wish though, the field is not 2000 yards but if you look North east east (i think is the correct way of describing the direction) there is just over 2000yards of fields (roughly)

well its not ideal from where i shoot from you can't see far at all and projectile retreval is hard because it lands in the middle of a planted field but if i'm lucky the crops are small :)

edit: and i'm not that lucky, i only have a 30yard range if i want to shoot accuratly or use a smaller cannon or for 'plinking' (by plinking i mean shooting spuds at the wall of my house and watching them explode on impact :D )

elitesniper, a threaded tee should cost no more than 5 bucks, if it's brass. I would personally just use galvanized fittings, because brass can get expensive.
