65BR: I no longer allow "round nose" ammunition to be used in my presence on Ground Squirrel safaris!
I do from 80 to 100 Ground Squirrel Hunts every year.
I haven't used it (round nose 22 L.R. ammo) myself in about 4 decades and no longer tolerate my Varminting friends and companions using round nose ammo either.
I just became tired and then sick of seeing the worthy little Varmints dragging themselves off into their holes after being struck with round nose ammo - not every time but WAY to often for me to enjoy a Ground Squirrel outing!
Way less "wounding" with quality hollow-point ammunition.
Case closed.
Hold into the wind
