Any magical mod to increase power AND get more shots per powerlet?

[wahoowad]

My 2300kt has been a lot of fun lately. I appreciate all the advice to help me get where I am at. 

I'd like to get another 25 fps (or more) out of it without losing any shots per powerlet, or maybe even extending the shot count. I'm seeing a difference in knockdown power on rats depending on when I am at the top of my power curve (~480 fps) and when I am down in the 20 - 30 shot range (~ 450 - 425 fps).

I considered a bulk CO2 tank but am finding I like powerlets just fine - easy, predictable, I know when to replace one. So anything less than 30 shots per powerlet is going to disappoint me

Those two items are mutually exclusive.  You cannot really get more power and at the same time increase your shot count per powerlet.

x2. Pick one or the other. Bulk feeding the gun is the only way to get both.

I know this might sound crazy but in both the 2300kt and the bnm2240 when I swapped in the pro-top and disco valve both shot count and power went up. Only a matter of maybe 5 more usable shots but still an increase.

OK, what is a simple mod to increase power yet retain the same shot count?

Short answer may be a longer barrel.


To increase fps using a cartridge (ambient temperature aside), you have to keep the valve open a little longer to allow more CO2 to flow to the back of the pellet. That can be accomplished with a lighter valve spring or heavier hammer spring. Keeping the valve open longer waste some amount of gas thereby driving your shot count down. Increasing the valve volume can help store more CO2 that will be delivered to the pellet. Again, more gas used; less shots.

13xx hammer spring, longer 18" barrel and a valve reducer? That should make more efficient use of the gas.

This is an interesting topic.   My (the wifes) 2400KT is on order and I have many things to learn about the co2 realm.  I'm going to keep updated on this topic, I'll need all the info I can get.

Thank you guys and happy shootin'!!

Actually, the 2300 comes with a valve reducer, doesn't it?

One of them does, the 2300S me thinks and not the 2300T.  Could be wrong.

What about the 2300KT?

Did you miss the first answer from Carl or what? 

Anti-Physics 101, I want more power from my engine but I also want better gas mileage 

Even if this anti-physics mod could be accomplished, let's say 500 fps at the first shot, you would still be below (your) unacceptable? 425 fps by shot 10 or 12.

An 18 inch barrel can get you another 20/30 fps and use the gas more efficently to achieve the higher fps, it is not going to increase shot count as it makes greater pellet speed from the same valve and co2 supply volume.

I don't believe that response was warranted? 

Carl's first answer was in response to increasing BOTH power AND shot count, which of course we all know is not going to happen.

Wahoowad's question about how to increase power yet retain the SAME shot count is a valid one IMO...for which the correct answer is yes, simply replace the stock barrel with a longer one...same amount of Co2 is being used, but the longer barrel will allow for more FPS...

[cherokeesteve]

If more power is what you're looking for (fpe) without dropping shot count you can also just try a heavier pellet. FPS can go down but impact power can go up.

Does the 2240 respond well to angleing the exhaust port and similar mods to smooth the path out of the valve to the pellet?  Those are standard mods for pumpers, I'm not sure about co2.  However every time the gas goes around a sharp corner it loses energy so smoothing that path will allow the same amount of gas to hit the pellet with more energy.
