Between 10 and about 22 degrees there ís no temperature issue for sure..And thats a cheapo Tau 7..
Temperature issues are só exagerrated!! They're nót crosmans, you know!
Near zero, than you might start to see some poi shift. Bút:
- thats what yr test shots are for, few clicks, solved
- is it surely the gun? I dont shoot well around zero either..
- pcp will react at these temps as well
99% of the CO2 matchpistols use cilinders. So shotcount is NOT an issue. Just fill up before a match. Thats what you do with pcp isnt it so why not with co2??
Filling CO2 cilinders is no problem at all. You can use simple fire bottles, or restaurant CO2 bottles.
ONLY issue in some countries, is the data on the cilinders. Bút thats equally true for older pcp's.
Another issue is changing weight/balance when co2 empties.

I really dont understand; they shot worldrecords with co2, won medals etc. Than why on EARTH should wé, normal shooting humans, nééd pcp?? We dont..We might wánt pcp, but dont nééd it.. If those pistols are good enough for world record, they're surely good enough for us normal match shooters arent they?
CO2 is by FAR good enough.
