I ordered one last night. I will probably just open the tp up and do the bstaley mod.

A few words about P-Rod shot count (and the various mysteries of anti-bounce devices).

Really do have to get posters to define what makes up "good shots" or "shots until I notice a drop".
 
Closer you are and/or the larger the target, the more velocity change you can get away with nand not notice the change.   I honestly don't know how much velocity change it would take to miss a soft drink can at 25 yards.

If you were aiming dead center on a typical 12oz. Al. can....that is about  2 1/2" to the bottom of the can...and at 25 yards, that comes out to about 10MOA...otherwise known as a "carp load".

If you were aiming dead center on a paint ball....that's about .34" to the bottom of the paintball...which is about 1.7MOA....still a good bit, but somthing many shooters wouldn't consider a whole lot.

With that in mind, here's 30 shots from a P-rod running all standard "guts".  Only a little polish, little lube, and a whole lot of pharting around with the adjustments.



NO...that's not "great"..it;s about 1.3 FPE/cuin..do think that with some time and effort,  most P-rods could do that without any "extra" parts.

So what do you take as the "real" shot count?

Pretty much would NOT miss a 20-25 yard paintball for at least 30 shots.

Here's a DISADVANTAGE to finding out: you can't get it out your mind once you know it (comes under the heading of trying to "unsee" something).

I Know in my mind, that a 5 or 6% varation isn't going to make a rat'sarse in my plinking or even bird hunting at 20-25 yards...yeat it preys on me... so I just give up and live at 4%.

Which comes out to filling to 2800psi, shooting 3 mags, and then just refilling back to 2800psi., load 3 mags, and shoot another 24 shots.

Interesting post Ribbonstone,I ordered mine not for intensive shooting,my .177 works quite good for this.
I needed a compact,easy to carry carbine for small pests at a tipical range of 20-25 yards.
I think 15 FPE of power is enough for my pourpose and i can live with a three mag shoot count if i have a good shoot placement.
I will try to adjust my Prod out of the box to see what it can do first,maybe the next step can be some port adjustement,i have a lathe and made some transfer port to play with is not a big deal,but first i must try to understand how the Prod react to the basic adjustments.

This is the best info you can get on the transfer port size to fps/fpe and shot count. I think that this should help give you a good idea of the port size to fps and then tune the Prod to shot count/fpe your liking.
