I've got two favourites. The first is my Savage 99 in 308 WIN. I shoot 165 grain Hornady Interlocks over H4895 out of it. It is my Opening Day gun. It only shots large bucks and then goes back on the rack.
The new favourite is my Ruger Hawkeye in 30-06. It too shoots 165 grainers over H4895.
Between them, they've scored 3 of the top five bucks at our camp.
