Got another question... teathering a regulated PCP?

[LDM]

I love shooting my .22 Brocock XL S6, which is unregulated, off my 80 cuft scuba tank once the tanks pressure has dropped below 2900 psi, the max fill pressure for the Brocock. It's like having a 80 cuft bottle gun My question is - Would it be Ok to shoot my .22 Wildcat while teathered to a tank. Not sure if it would hurt the regulator, but can't imagin it would. I also own a CF tank that I get filled to 4500 psi but it doesn't take long for that tank to drop below the 230 bar max filling level for the Wildcat, and I hate running to the scuba shop. Shooting teathered would allow me to use my tanks longer between filling them to their max level. Might be time to invest in a compressor though!

Why would it hurt the gun? The only difference is loke you say, much more air! But only do it after 230 bar like you said, too high pressure is not good in any gun, but 230 is fine. Enjoy all that shooting!

That's what I thought Erik. Thanks!

You can use almost any PCP gun teathered as long as you don't use a tank at a higher pressure that the gun is rated for.

In theory it might give you better consistency by reducing the drop in pressure between shots. 

You can also buy an external regulator to use with teathered tank set-up and that would allow you to use tanks at higher pressures without damaging the gun.

Thanks Zebra! I shoot from a bench much of the time and I hate wasting the air you loose with every charge from a tank you do. Going to keep em tethered when paper punching... untethered when the starlings show up!

Oh, and tethered once the tank pressure has dropped below the max operating pressure of the gun I'm shooting.... of course

Have you tried running it through the chrony while tethered? If you tether your unregulated airgun to an external regulator and tank, does it act like a regulated gun with low ES and SD? I also have a Brocock Contour S6 Elite but I get limited shots per fill. Especially with a hand pump.

 

[LDM]

I have, but it was a long time ago. It was very consistant as I recall, with a low ES. The one drawback to the XL S6 is the low shot count. I think I get about 15 good consistant shots per fill, but that is plenty for hunting. The gun is so accurate and light that I can overlook the low shot count when not tethered. Get yourself a scuba tank if you live in an area where you can get it filled. You should be able to find a tank for $125-150.

I always shoot off the bench tethered. I do use a high pressure regulator because I start with a 4500 psig tank. http://www.airgunnation.com/topic/tethering-tank-to-rifle/

I tether my PCP's. I have a regulator between my 4500 psi, 66 cu.ft. carbon fiber tank and my air rifle. With the regulator separating the CF tank and the air rifle, I can guarantee that the air rifle will never be subjected to more pressure that it can handle. On the outgoing side of my regulator, I set it at 2900 psi and forget it - even though my Mrod can handle 3000 psi.
