My experience is with ground squirrels rather than edible tree squirrels. On body hits ground squirrels die quickly, and sometimes rather dramatically, when hit with hollow points - whereas hitting them with round nose they usually make it back to their hole to die a lingering death or to be eaten by their brethern.
The ground squirrels in the west are smaller and quite often a round nose will go through them with little apparent damage but the hollow points disable them.

True and when you have a 500 shot day at ground squirrels scampering everywhere you look - even had them run between my legs sitting on my shooting stool , you see what kills and what is just ok .
CCI SV HP - like 3-4cents each back in 07--08 - just shoot them through the chest and they are dead right htere .
