Having lent my trusty air rifle to a young lad some time ago, (and if truth be told, not wanting to ask for it back as I know he uses it regularly and can't afford one of his own) I have been planning an assault on the ever growing rat population at my chicken run. This could be a good opportunity for me to dip my toe in the water of a PCP rifle. I'm talking sub 12 ft lb here, something light and small ish so that I can use it to teach my little boy when he's older. A friend has an air arms s400 with charging gear, and I can use this so I was hoping that something like a S200 might fit the bill. Does anyone have any advice to offer? I'm hoping the charging gear is the same on both rifles to make life simple. Any comments would be appreciated.
