I used one shot one time resulting in a stuck case right off the bat. Switched to Forster Sportlube and haven't stuck a case since. I think Hornady case lube is same product, different label as I have used both w/same results.
Had heard all the good reports on Imperial, so when I started loading for the WSSM's, bought a can since the extra thick case of the WSSM's require a lot of sizing. These cases squalled like a banshee w/Imperial (but I will say, never stuck a case). Switched back to Hornady and no more groaning during sizing operation. IMO, Hornady is better lube than the Imperial, based on use on/WSSM cases.
