[QUOTE="Hugnot, post: 3052152, member: 115658"] I use Lee collet dies but never had the top aluminum cap bust. The aluminum cap is designed for expected forces but huge ram forces [B]^^^^^[/B] can be exerted with compound lever presses such as my RCBS Rockchucker press. When I get a new Lee collet die I disassemble it and polish the top of the steel collet with 400- 600 grit to remove any burrs caused by machining the slots that allow compression. I also polish the inner cone surfaces of the cylinder that compresses the collet. Upon completing sizing I disassemble the inner working & clean everything with Hornady One Shot cleaner & lube. Should the collet get stuck inside the steel compressing cylinder the the brass case will be squashed, like crumpled as the case neck will not slide between the compressed collet & mandrel. The new steel mandrel/decap rod has been redesigned with stepped diameters allowing easy guiding into case mouths. Lee stuff is generally well engineered, inexpensive & innovative but a little rough. I avoid Lee F/L dies because every one that I have uses does a massive small base type resize that is excessive for my bolt gun use. [/QUOTE]
