I have a single pump (spring piston) 177, can't remember the brand... it's pretty accurate, at least across my backyard. I haven't shot it in quite a while... guess I should clean it up and try it out...
I have a Handi Rifle in .22 Hornet that I haven't shot much. I used to shoot a Contender Carbine in .22 K-Hornet, but ended up selling it. I rented a chamber reamer, and changed my Hornet to a K-Hornet yesterday. I still had some ammo loaded up, and I used those as a go-gauge. They drop in the chamber perfectly. I will try to get it out and test fire it in the next few days.... it will be good to have a K Hornet again... it's a zippy little cartridge..
