Slovak Airgun Field Target Association

Hello,

Instead of using compressed air, I used the little air CO2 cartridges from my mountain bike days. One 16 gram cartridge will put about 36 lbs in the bag, only need 30.
Traveled to Tahoe last weekend (500 miles). Lost 6 lbs of air.
Refilled and lost another 6 lbs when I got back. Took the trailer off, reduced the pressure to 12 while riding empty. Checked and it lost 6 lbs again.
