Silly question but how would one employ lube when using a progressive? Is it not required?
Generally, you don't need lube for sizing straight walled cases with carbide dies, although some people lube cases to reduce sizing effort.
Bottleneck rifle cases do require lube for sizing. Because bottleneck cases need to be trimmed, they are typically sized and trimmed (if required) separately from all the other operations. This can be done either with a single stage press for resizing or two passes through the progressive; one to size and one to do everything else.
