I read an article in my Sept/October edition of BASC magazine by Jonathan Young singing the praises of co2 even in cold weather(tested a "Gas Air rifle " at 30 metres against a hard target at 30 metre,s in January 2 % centigrade plus wind chill) Recorded regular hard hits stating some are as good as expensive pcp rifle,s NOW Matt Manning in his book "Hunting with air rifle,s" The complete guide dismiss,s them and does not even give them book space. What does the people on this Great Forum Think these days
