Afternoon everyone,
Sorry if I made that title sound stupid. I have a 2078A that I bought late last year. Couldn't be happier with it but have a question. Using two 12mg Co2 cartridges loaded together how many shots should I be able to fire without losing pressure enough to cause it to shoot low. There is no pressure gauge on this rifle so I have to count. I tried it a little while ago and after about 40 rounds it started losing speed and elevation. I thought perhaps it was time to change to fresh power cartridges and slowly began to unscrew the cap. It went about 1/2 turn and stopped. I tried another shot and saw it had gotten speed and elevation again as when I first started shooting. I got another 40 or so rounds before losing power again and after following procedure in the instructions I was able to completely remove the cap and take both cartridges out. These cartridges had been installed about a month ago and were at full capacity today when I started. Apparently I was only getting power from one cartridge until I turned that cap open about 1/4 turn or so and then I got power from the second one. I don't know just now where the manual is for this rifle so I need to know if unscrewing the cap about 1/2 turn or so is normal and required to use both cartridges. Normally this wouldn't be a big deal but I bought this for some casual match shooting and the task is 60 rounds in 75 minutes. While that is easy enough I don't want to waste any rounds to low power if I can avoid it. Is this a standard method on this rifle for accessing full power in both cartridges with no further adjustments needed? Thanks.
