Looking great! Now lets see some groups.

Sure, I am building a shooting rest

Here is my shooting rest, DIY from a ham holder

This device is just for testing, I also have a Caldwell shooting bag.

Today I just had time for one group of six .22 H&N Barracuda at 25 meters.

.22 JSB 18.1 gr with a 20" barrel at about 130 bar reg pressure = 840 ES 2.5 and after 20 shots drops below reg (250-130).
I shall be satisfied but if I raise the speed the ES opens up so just leave it here.
Still I feel that I am loosing some air efficiency here but cannot find a lill harder HS and also I don't want to raise the reg higher, or at least to have some VS adjustments...

Hate to be that guy to bump an old thread but here I am.

I luv my pp750 and have fired a few thousand rounds with zero issues, no leaks nada!

I have a gauge block, longer barrel (10.5"), chrony and other goodies in transit. Wish me luck!

Thanks for posting pictures to avoid "surprises". These PCP have quite the learning curve.

I am overwhelmed at the size of this forum, It will take a month or so to navigate this place.

Thank you James for the added informational links, much appreciated!

Here's mine. Just switched the stock recently and put the lpvo on it. It's sighted in now so I need to really get to shooting.

Now there is a bottled option...

Wes has more of those kits coming, called the PP750 valve and regulator. Very nice add on! $120.00 Canadian and of course bottle is extra.

I just went with the Plenum Gauge Block as I want to keep mine compact. Hopefully my package will show up next week sometime.
Luv my PP750!
