I still use a S410 carbine at 12 fpe. I love the S410 platform. I, in fact, like the S 410 bolt action version because I am find manipulating a traditional bolt much quicker than swinging out a sidelever and closing it. So I have two S410s! The carbine has exceptional balance for fast offhand shooting and like all AA pcps I have ever shot, shoot really tiny groups.
I will make a bold claim and state that as a general purpose pcp, the AA S410/ 510 series is the best ever built. They are extremely reliable-- never had one that failed-- have excellent triggers and outstanding accuracy. Have you noticed how no one ever posts they have an issue with an S 410/ 510 series rifle? For low to medium powered pcps, Air Arms builds the most reliable, gimmick free, out of the box superb shooting airguns.
