I have the Huntsman Revere regulated .22. It is one beautiful gun. Cocking is as smooth as everyone says.
I had a Air Arms S510 and it was a work of art too. I constantly buy, try and sell. I don’t know why, I do enjoy trying all kinds of guns. I just got an Air Arms HFT 500 and oh man is it nice. I’ve only fired it 25’ in the basement and it’s literally one hole. The Air Arms S410 looks as beautiful as the Huntsman. As accurate as my S510 and HFT 500 was and is, I would not hesitate on the S410. It is on my want list as well.
BTW, the Huntsman is extremely accurate as well. The Huntsman reminds me of a lever action 30/30 rifle, it’s rock solid.
Edit: The S410, from what I saw on Air Arms site, is a bolt style cocking. Having owned a Marauder that was bolt cocking and I will say I like the side cocking like most PCP’s. But it would not keep me from buying an S410.
