Re: RCBS Carbide dies
Actually the numbers I have seen says between 100,000 and 200,000 rounds, depending on the amount and type lube used, will cause the start of egg shaped or oversized brass in full length sizing operations.
That's a lot for one person to shoot in a bolt action rifle. But if loading for 3 or 4 people shooting semi autos or full auto, that number can become realistic.
