I am currently debating on which rifle to buy for target shooting and a little bit of varmint control.... I want something that will have good knock down power up to 300 yds. but yet a round that isnt very expensive to purchase box after box..... my mind is made on the kind of rifle: Remington XR 100 Rangemaster but im undecided on the caliber of it.... coming in Ruger 204, 223, and 22-250 ... I know the 22-250 would probably be my best bet but I already own a 22-250 so thats kinda out of the picture.... I myself am leaning towards the 204 but there's where money comes in for ammunition.... what would you guys do?
