Re: Niel Waltz die
No doubt on the die quality, but unfortunately my die is ultra-clean.
I guess it is just the fact that the bullet expands inside the die as a result of the upper pressure, and the wax sticks to the die bore. This, only with certain type of ammos, not with all.
Thought about actually slightly lubing the die bore, but I'm afraid that's going to mess up the bullet's wax.
