I've read either in GUNS or maybe the same article above in SHOOTERS that show 10 shot groups less than 1 inch consistanly at 100 yards. Also the foot pounds are around 75 and speed still over 1200 fps at 200 yards.
This would put the usable range,depending on what your hunting, at around 100 yards to 150 max. However, with the accuracy of this little rifle there is no reason one could not take a coyote with a head shoot at 100 yards, no wind!
I think if they can keep the price of the bullets down to a very reasonable cost, this little rifle will definatly replace the 22 mag. Time will tell...
Also, you may consider a 22-250 with light bullet heads. A .223 for the ranges you are talking about would be an excellent choice, but if that long rang shot comes up the 22-250 would easier to compensate for the range.
