The 233 WSSM only adds about 5% more velocity than the 22-250 using 20% more powder.
That 1% velocity increase per 5% powder increase is also seen when comparing the 223 and the 22-250, The 22-250 shows a dramatic 20% veocity increase over the 223 but it does it by using twice as much powder! (A 100% increase)
The 22-250 is a great cartridge and will work well in steady hands on coyotes out to the far side of 400 yards. The 223 is another great cartridge but it starts to shed velocity quickly after 250 yards or so. Even though at longer ranges the energy figures are still OK the rainbow trajectory, and the poor wind-bucking properties of a slow moving .22 calibre bullet combine to make good marksmanship difficult.
The question then is at what range do you expect to be shooting? If most of your shots will be inside of 300 yards the 223 will be more than adequate. If however you are looking at longer shots the 22-250 (or 220 Swift or 223 wssm) will be a much better choice.
As for fur-friendly bullets I personally have fallen in love with the 60 grain Nosler Partition out of my 22-250. Small enty and exit holes are the norm if you avoid hitting shoulder bones, (If you do put one through the shoulder the Partition will act like a FMJ and blow hundreds of bone fragments out through the off side! ) The partition also works very well on wolves if you happen to bring some in while calling coyotes!
