I think shadowrider has it right. I've tested almost every kind of lube out there (well for cases anyhow). Imperial and Hornady Unique are about the best you can buy. None of the aerosol lubes have given me any luck. I've had many cases incredibly hard to remove from the die and a few stuck cases. I'd give it a try, It's only a few bucks. I've also heard that the Mink Oil paste (shoe polish) you get at WalMart is exactly the same thing as Hornady Unique. I'd probably start with that since you can just get it for about $3 on your next trip to the store.
