Stone glacier packs and a pedal bike with panniers (depending on location). Easy to push a bike around and saves your back/knees.
When I hunted deer back east, we used wheelbarrows. They're made to push heavy loads and a big inflatable tire works well on any decent kind of trail. We'd go 3-4 miles in.
Some years ago, my partner and I used a wheelbarrow to pack an elk 4 miles. It was a 4x4 and we got it all in 1 trip. Granted, it was on an old logging road and 95% downhill. We used a rope so both of us could pull on the occasional uphill stretch.
Hint: don't try this with a cheap Walmart wheelbarrow. They'll fall apart with that much weight on rough trails. Only use a quality heavy duty one.
