I’ve taken 3 deer with 10mm. One was with a factory XTP as I shot it (legally In season) at 30’ with my stock G20, stock sights while coming up my driveway. One was at 49 yards from my side door after I’d gone in for snacks, with the stock G40 and RDS, the other at 25 yards from my roof. Both were my 180gr XTP loads. The farthest I tracked was about 20 yards. I’ve yet to test my 200gr hard cast nuclear loads against live targets, but they shoot just fine out of my stock barrel G40.
Nice hunting grounds!!!
