I must be the odd guy out.
Have tried the stuff 2x and felt it was harder to size than standard brass. Just a year ago I sized 50 R-P 30-06 brass. Felt like I was trying to size a chunk of cast iron. Maybe the die is a fuzz tight I don't know but that was enough for me. Sized 50 pieces of same except for standard brass at the same time, slick as butter in and out of the die.
Had some peel off as well while cleaning up case mouths years ago which is why I hadn't tried it since.
What sizing lube to you use?
Yes, nickel-plated brass tends to be harder to resize, but have found the job is pretty easy with Imperial wax.
