I also have used the 60:40 beeswax Vasaline lube and it worked fine in my .458 at 2,200fps with my WW bullets, hardened or as-cast.

The larger bores are not as particular to speed/pressure/lube as the smaller bores.

I use a hot plate - bullets on tray - pound the melted lube around them- adjusting the height is needed with more lube. Once totally melted and quite warm, I cut the heat and let the lube solidify.

I then use a ctg. case with the base drilled for a 3" long 1/4" or 3/8" bolt with a 'washer' or nut threaded on the end. The washer or nut is just under case mouth diameter.

I push this tool down over the bullet, 1/4 turn, and pull up. The bullet, inside the case neck, comes up with the 'cake cutter'.

I push with my thumb on the top of the bolt and it pushes the bullet out onto the table, base down and ready for loading. It's fast, non-messy and easy to set up.

When using a ctg. case as the cake cutter, the bullet's grooves are perfectly filled with lube.
