I used 50% lamb tallow & 50% beeswax in my first batch of lube; it was ok, but still pretty crunchy. I wound up adding quite a bit of olive oil to get it to sort of a "cool margarine" texture at room temperature.
The tallow itself is pretty soft on a non-winter day. I think it would be too soft to carry around in any container that isn't completely waterproof (except in February!).
If I ever run out of batch #1 (it turned out to be a lot), I think I'll use about 25% beeswax to firm up the tallow, and add wax if needed to get a consistency I like.
