We actually didn't hunt with the horses per se. We rented a ride in and out. The outfitter dropped us and our camp gear off and then came back to haul us out. There was just the two of us, so it wasn't very much stuff. We even rented a wall tent and stove in Denver, so daughter Jane wouldn't have to put up with the trash I normally get by on. Good thing--got very cold...
IIRC, she used 150g AB in her rifle. I wouldn't hesitate to use the 150g BT.
