Streamline tune hiccup

[Pepper]

Noticed a rattle in my gun , took of tank and valve retaining spring and nut and fell out into my hand . Was a pia to get back in but it’s all coming together now . Shoots 34s in the 890sN

Same damn thing happened to mine. Had to make a custom spanner to tighten it back up.

An Allen wrench fits the retainer. 3 or 4 mm I think.

What kind of shot count are you getting at those speeds? Mine shoots the 25gr just barely over 900, but the 34s are much slower. Plus, how is accuracy? I wouldn't be opposed to tuning on mine if I could get the same speeds and accuracy I'm getting with the 25gr. Put one right between the eyes of a racoon last night at 40 yards.

Reg @ 140 bar I assume? I wonder what size porting from valve to barrel the streamline runs? Anyone tear one open and measure?
