Help - 1st PCP choice - Urban, Fortitude, or P-Rod - today?

[Marc]

Reporting in - just ordered the Urban!  Tanks for all the help!

So one question on the Urban - if I turn the power down do you think I can get much more for consistent shots per fill?  I'd be totally happy with a 15 FPE set up for my needs.

Finally!

 

Congrats

Oh yes!  Now I need to order the hand pump and some ammo.  AoA and Pyramyd have what I want - you guys prefer either one?

I order from both and have never had a glitch so far.

As for pumps, I order from Amazon.

The GX pump that I bought from them (Amazon/Ankul) got fully refunded (about $160 +) 'cuz it was not working at first due to a too deep foster.

I experimented with it and installed an extra Harbor Freight O-ring, then I was able to air my tube with gusto!

Thanks - you guys have been a ton of help!

Think you’ll like the Urban….a lot of us like it as well.

Haven’t tried quite that low.


With non regulated PCP’s with one control (the striker spring tension), the changes aren’t in isolation.  Change one thing, and other things also change.

What normally happens when you decrease the striker spring tension lower..both  power AND sweet spot pressure changes..   So cranked up, might give 28 foot pounds for 20 shots at 3200-2200psi….cranked down, might get 40 shots at 20 foot pounds  at 2800-1600.

Might not really care about velocity changes that much.  Just plinking at short range (like 20 or 25 yards), it takes a whole lot of velocity change to make a difference on target.

You’d think not….but the change in velocity is gradual.

(not from an urban….from one with about the same air volume)

Velocity variation in any one of the 5 shots groups is small….so the pellets tend to cluster.

The average velocity of each 5 shot group shows greater velocity change...so the cluster locations rise and fall.... makes like a bell curve.

By the chronograph, shots #10- #38 are the “sweet spot”….but just plinking in the back yard, see no reason not to use all 50 shots.

Thank you.  Anything over 12 FPE is more than I need (for now), so the more shots the better.  I don't have a chronograph, so I'll just have to watch results to figure things out.

All good first choices IMO. Fortitude would be my pick. I like long traditional looking rifles so that is my bias. 5 year warranty helps. Lots of great suggestions here though. Happy shooting!

Might grab a Fortitude when the .22 cal. models are back in stock.  Now that I'll have a pump, well...............And I did go with a Hill.
