Hi everyone. I'm looking for some advice about co2 guns. I've only ever shot springers before but my son would like a co2 rifle. We watched Andy's review of the Webley nemesis x kit and were really impressed. Can the more experienced shooters advise, should co2 capsules be removed immediately, or can they be left in for a few days, weeks etc. I've read lots online and some say always leave in others say empty and remove after each use. The gun we like takes 88g capsules so I don't like the idea of firing a few shots then having to empty and remove. like I say, this is all new to me. Look forward to your replies, thanks.
