I recently did some tests with Neolube on .338LM cases on an AMP Press and saw a significant reduction in seating force variation. However I haven’t been able to get out to test them for velocity variation, but based on past experience with lowSD seating there should be some improvement.
Good idea,
@rustyinbend I’ve been using Imperial Dry Lube prior to mandrel but if you’re going to use neolube anyway, why not during sizing?
