I bought a Ruger 77 in .450. First season weather was crap of course, but I did hand it to the kid I was sharing a blind with as he wasn’t sure his gun was good enough for the shot. He threaded the bullet between to trees about 2 feet apart and put a mature doe down so hard and fast at 141 yards I barely saw her drop in her tracks.
I used the Hornady 250gr FTX loaded ammo in the black box. Intend to reload for it eventually. Very impressed so far.
