High temp lubes are not a very good idea in any event. Hard lubes tend to not come completely off the bullet so it puts them out of balance. When you retrieve a bullet from the back stop and it has 1/2 or 1/4 of a lube groove still full of lube you can assume the bullet was not well balanced.
Alox is a very poor choice for BP. Its shortcomings in the use is the reason SPG and the later BP lubes came into being.
