The .204 is and aweome caliber for varmints of any type I hunt for fur and thats one of my rifles, but their right. The .204 is not the best caliber for out past 375. What you need to do is get a .223 ackley improved. Some argue with that but its a great gun. My .223 ackley is shooting only 240 fps slower than a 22-250. To tell you the truth I really dont like to shoot yotes, foxes, etc. out past 375-400. Ive only done it twice, the 1st time I was only messing around not thinking that I could hit it till i hit it behing the ear.lol But anyway, if you are going to hunt the smaller varmints out past 450 than you need either a .223 ackley improved. Actually a lot of long range hunters in MO, use a 25-06 ackley for g-hogs and such. But I hope I have helped you a little.
