Do not know if this will help you or not, but I do hunt ground squirrels in the spring with a Hornady 10mm200grain XTP and a blue 40/50cal sabot. The bullet is very inexpensive and it is fun to shoot. I am shooting 110 grains pf T7-2f, easily shooting squirrels from 25 and beyond 100 yards with this load. Not much left of the animal after contact with the XTP though.
