Just used Imperial wax for the first time to resize a couple hundred pieces of brass. It was very fast, easy to use, and had zero problems with tight cases. Just a dab on your thumb and index finger is enough to coat half a dozen piece of brass and a light swipe across the top of the can and your good to go for another half dozen. You could easily resize a few thousand pieces of brass using just one little 2oz tin. If any of you are still using that crap RCBS stuff you need get yourself a tin of this stuff. I have a couple cans of OneShot sitting on bench but I don't forsee myself using them anytime soon...
