Moonhunt.
The dies that need no lube have carbide inserts in the sizing die.
These carbide sizing dies are usually only found in Pistol Calibres.
Go for the dies that you can afford.
Lee RGB dies are excellent value for money and will last a lifetime if you look after them.
Forster Bench Rest dies are also very good dies that will last you a lifetime if you look after them.
However they are more than three times the price of Lee RGB dies and unless your shooting serious competitions you wont notice any difference on the Deer.
Cheers
Pete
