Spotting hits, which is easier with the smaller rounds does have some value, to me at least. There have been times I have hit deer with standard .270/.308/.300 rounds, which during recoil I couldn't confirm the deer's reaction to the shot: if it went down immediately, if it turned around and ran the way it came from, etc. This is generally only an issue in tight cover, but it has been an issue for me before.
That is one of many advantages to using smaller rounds. It isn't all just about girly men not being able to tolerate that dreaded .270 Win recoil. That is a non issue that many anti .22 CF people seem to think is. I will say though, that to be proficient at 500+ yards I have had to put a lot of rounds downrange, to which standard deer rifle recoil and round cost has caused me to go smaller.
