I am branching off another thread rather than hijack it with a question. I mentioned my powder measure is down because of a broken small part. I am looking to order a replacement and looking at the parts list I started noticing all the small replacement parts the vendor sells for it. I already keep a lot of small/spare parts for the guns like extractors, ejectors, springs, screws, pins, etc. and don't really want to inventory more parts. However, I'm back to hand dippers with my powder drop out of order. Do you order small parts only when needed or do you keep a supply of spares for your favorite presses and equipment?
