Tuning  Regulator pressure VS Hammer Spring tension

Apologies for bringing up an oldie, but a great ttuning thread imo.

I have a thought for conversation...,My .22 zelos likes 870 fps for the 18.13 pellets. I have gotten there bumping up the reg, and backing off he h.s., and vice versa with the same group sizes. What are your thoughts.

My set up with...
1. Higher reg psi, and less hammer spring feels ,and sounds sluggish compared to...

2. Lower reg. and up the hammer spring? Seems snappiier, and quiet.

let's leave shot count, sd and es at the proverbial door for now. I am more interested in finding if your rig groups better with a higher reg.?, or more H.S. Tension to get to the same fps?

Thanks for your ideas....

Brocock/BRK  Delta Wolf Help

I did install the ultra valve last year. I never had any issues shooting heavier pellets? I did speak with AOA yesterday and they emailed me the programing for the ultra valve. I thought I had already installed it when I installed the valve but now I'm not sure. Will get that installed today and let you guys know if this works!
So, did it work?

HW/Weihrauch  Beeman 77 MK1 ball detent fixed

That's cool, Ron. You know I would have had to make my own, right?
Should be a Weihrauch recall bulletin?
Thought about you lately, waiting to hear how you made out.

Shifts a little funny, 3rd and 4th. I'll replace the gear lube for him.

Diana  High quality German engineering........

I bought a Diana Outlaw Gen 2, engineered in Germany and manufactured in China under German supervision over the winter. I would put this incredibly accurate and well engineered PCP against any other manufactured PCP at twice the cost or more. On my 4th tin of heavy JSB Exact Monster 13.43gr .177 pellets....the folks at our range not only tried it, but several purchased during the July 4 discount period. Yes incredibly accurate and scoped. I also have a Diana Airbug pistol .177 that is an accurate as anyone else's CO2 or PCP or whatever you care to compare with. Yes German made in China. Just watch the Airbug videos! I even bought a silencer for $30 made in USA (Houston) that make the report sound like spitting tobacco. Just a ball at 30 yards, open adjustable iron sights and 2 stage trigger.....amazing. Have fun complaining about top quality Chinese products.
