You can set the tune for the power level and shot count you prefer. For example; in .25 caliber and using a 3000 psi fill pressure, shoot 25.39 grain pellets at over 900 fps for about 24 shots (more power uses up the air supply faster), or shoot the 25.39 grain pellets at around 775 fps for around 65 shots (very quiet shooting tune), or tune for something in the middle (compromise between power and shot count). 40+ shots at around 842 feet per second with 25.39 grain pellets is a very popular tune.
Excellent choice for pellet Or slug shooters.

+ Includes a drill bit to open up the air inlet port in your rifle’s barrel -only (.22 and .25 caliber). No need to open up the breech.
For .177 caliber Rifles, no drilling is necessary with the .177 kit. No need to open up the barrels air inlet port any larger, leave the port the stock size, which is large enough. *The .177 kit is also an excellent choice for lower powered .22 caliber and .25 caliber rifles. Great for backyard shooters, pest control or for anyone that does not necessarily need higher power from their .22 or .25 rifle. You will get a lot of shots per fill and will fill the rifles air reservoir less often. Very quite shooting too.
