Hornady one shot is a great product. A little tip, put your brass into your loading block and set the edge of it on a piece of 2x4 to tilt it. Spray you cases so that the spray lubes the inside of the case mouth. A light coating is all that you need. But you have to allow it to dry.
Also, before you begin sizing - if you used the old type of case lube, you have to take your sizing die apart and clean it out. Acetone or gun scrubber does a good job.
Also you don't have to worry about case shoulder dents like you did with the "other" case lube. It doesn't have to be removed as it isn't supposed to comtaminate powder or primers. I usually size my cases and throw them into the tumbler for about 1/2 hour.
