Hi i finally got my first gun after months of shooting with other peoples. I decided to get a umerex 850 airmagnum, is this a good choice? since it is a co2 powered air rifle it will cost me on catridges, is there a cheaper way to power it i.e. refillable ones or using the 12g adapter? i didnt know if the 12 g cartridges are refillable, or if 88g ones are refillable?
also i wanted to get a bipod for it, i've made a temporary one at work just to perch on whilst out this weekend. does anyone know if there are simple detachable ones you can buy rather than getting the stock studded to fit, sa
