Considered getting one based on my love of the outdoors. From what I understand, you can get almost .357 power. And hold many more of those little shiny things. Dont wanna spend more than $800. Glock 20, Tangfolio EAA Witness I think they are around $700. What can I expect in ammo costs if I am to practice with this hot round. Basically tell me everything you know and then some...thanks in advance fellas.
