Consistent accuracy at 100 yards is a lofty goal. I think that means a HP .22 as a minimum. I think we can make a mistake by thinking, well, most of my maximum range is, say 50-60 yards, and the 80-100 yard distance is only occasional. Even if the extended distance is infrequent, you still want to be able to hit it, and a standard power rifle, IMO, will not offer that kind of comfort. I would consider three rifles, RAW and Red Wolf, both in HP version, and and FX Boss (30 cal). The 100 yard requirement really cuts down the population of suitable candidates.
