This might be old hat to some folks....I recently bought neck-sizing dies for the Whelen. Years ago, I bought what I thought was Imperial Die Wax. I went to open it and it was full of black powder like graphite. I read the label again (with my glasses on), it said, Imperial Dry-Neck-Lube. It has been in my shop all this time, and I decided to try it. Just dip the neck in the powder and run it through the die. It worked fantastic. No cleaning lube off the cases, no powder sticking in the neck, no chances of contaminated primers. This is a whole new world. I am going to have to get more neck-dies. It will probably work great for any straight wall pistol or rifle cases.
I wish I knew about this a long time ago. I have a ton of money in full-length dies.
