KP2 garbage efficiency

I played with my KP2 for the first time today, and I love it.

But I HATE the horrible efficiency I'm getting with it! I was under the impression I could expect 15 or so usable shots off a 12gram with it bone stock, but I'm only getting 8!

Far as I know, it's got bone stock internals and valve. Chplnstone would know better since he actually pulled it, and I have a valve tool so if need be I can crack it open.

What are possible causes/solutions?

Please don't just say send it to PPS. I just got the damn thing back from getting worked on, and I'm morally opposed to sending it away again for a length.

Thankee!

see if your paint matches your barrel. if it is was to small and rolling out you will lose some efficiency that way and if you have a chrono i would check your velocity... thats all i can think off for now but im sure some others will have some more things you can do

Need to compare paintball size to barrel diameter. The smaller the ball, the more CO2 gas will be used. Plus depending which brand of 12 gram, how accurate is the fill in the powerlet?

depending on what tools you have or have access to will determine what "you" can do for efficiency.

it needs a valve job done to it. that will require mods to the bolt, valve body, valve stem, and the air port between the bottom tube and barrel.

paint to barrel match has little to do with it in this situation. it needs valve work.

All might not be lost-
A Sheridan using a 12 gram is not a good winter toy.
I don't take mine out unless the temperature is above 45 degrees, otherwise you are just shooting liquid, which is very inefficient.
What was the temperature you were using it in?
What did it chrono at?

no problem GOofy.

BretG hit the nail on the head about the temp. temp will make a world of difference. you should still consider valve work too.

I was indoors, so the temperature was decent. It was chronied around 240.

Are there any methods that I can try to improve it? Would stripping and cleaning it improve anything?

It's punching really large holes in the 12grams, way bigger than anything else I have used. Could that be a factor?

try first eliminate these things

temperature play at 65F or higher
paint to barrel match must be spot on 689 or higher for size it also the consistency of size and roundness or critical
exhaust valve may be turned 90 to the port for transfer this will kill efficncy
