I’ve found out last year that going for a walk on a bright sunny windless day but at -10 or colder can be very productive.
Quiet snow on the ground is helpful.
My go to deer rifle is a Ruger American Ranch in 7.62x39. I’ve killed many deer with it so far. Before I started reloading my go to was the Hornady Black with the 123gr SST. Very accurate and killed well.
I now load Barnes 123gr TSX and they are loaded hot. Have not been able to take anything...
