what kind of mods have you done grumpy? Ive managed to wring a fair bit out of my hipac'd 2240

Hi David,

Welcome to Airguns forum. Here is a thread on this very crosman but I was only using 12 gram co2 http://www.airgunsforum.com/showthread.php?t=100

Thx Grumpy. I've recently starting playing with co2 in my Hipac 2240. Had done plenty of testing with hpa and was pretty pleased at the power and shot count with the little bitty bit of air. With a good fill of co2 i get 55-60 shots @ 560 fps with a 14 inch barrel and stock hammer spring. Have a 24 incher for when i want to get some big numbers on hpa.

I hope to build a separate Hipac 2260 for co2. Getting those high shot counts is so nice. Please shoot some pics and document you build here when you can.
