Although I would say boots and or pack would be among the top of the list, I am still yet to find a pair of boots that has simply stunned me... My Cabelas Elk Hunters by Danner have been great, but on 5+ mile days I develop blisters or hot spots. My Eberlestock Dragonfly is awesome, but on heavy loads the straps leave something to be desired (they are 'soft' and fold twist and turn easily and need more padding). Most any Remington bolt ,(721, 700, 788 etc) will most likely shoot straight enough....
Having said that, I would say my Leica Optics are most important... Duovids, spotting scope and range finder. If you cant see it, you cant shoot it.
Second would probably be my Springfield XD-40... I hunt near the border and carry this pistol every second I am out there.. I have never needed it in a self defense type of scenario, but if I ever do, I trust my life on it and that is comforting knowing it is on my hip at all times.
