   Billbobnz thanks for that it will help me figure out the plenum I will make it a bit bigger as I like to run heavier pellets.

kruzaroad it is a very nice little gun I was quite surprised at the weight too.

The bottle heater is a good idea not sure what could be use as it will need some kind of thermistor to regulate the heating element but I'm sure someone with knowledge of electronics could easily make an insulated sock with heater using a lithium battery or something, it would be greate for night shooting.

	It's a sweet little gun too bb. I rather liked it. Was expecting it to be heavier but it's still preety light. 308, there was some one talking earlier in the year about putting a heating pad around the co2 bottle to control the temp veriation. What happened with that idea and if it became part of build I have no idea.

	565fps is with JSB Stratton Jumbos 15.89 grn pellets. These preform the most accurate through the gun.

	Hi guys what is the average FPE or FPS you get out of a modified cr600? I am trying to work out a plenum size and from my research it is recommended to have 1cc per FPE. I know co2 gas pressure can change a lot but if I can make the plenum a bit bigger it should hopefully help when the pressure is on the low side.
