If they weren't dented prior to sizing, yes.
I've switched to Imperial sizing wax. It takes very little to ensure a case won't stick, but leave excess on the neck/shoulder and it too will cause denting. Wipe your finger across the wax, rub it on, resize. It wipes off easily with a rag or paper towel also.
The neck and shoulder area needs the barest of lube anyhow. It's the case body, particularly the web area, that will bind in the die. Make sure the lower end is sufficiently lubed.
The good part is shoulder denting, unless you're packing powder in the case to the max, isn't a problem and irons out on the next firing.
