I have AA s410 in .22 and .177 as well as an HW100s in .22, and must say that the one one most used is the HW100. I have fitted a Venow cylinder which makes it better balanced and a little lighter. I have used a Pellpax sample pack for each of my guns and come back to using AA Field pellets in all of them, still got to try JSB pellets yet. I may well sell both AA to get another HW100s in .177.

Regards,
Kevin.
