You cannot beat imo the hw100 Mark, i have 1 in .177 cal with the Dr Bob bottle conversion on it a 400cc bottle the amount of shots per refill is fantastic, i have used this pcp for at least 4 yrs now its taken loads of bunnies , tree rats, rats, wood pigeons , its a great Night vision gun with my Nite-Site NS-Wolf aboard, along with my .20 cal daystate huntsman classic these two airguns are my favourite pcp,s
enjoy your hw100 its the BEST.
