I purchased this manual to see what secrets it contains. Not much over the Lyman manual, but a bit different take on casting technique. If you were new to casting it'd be helpful, but I wouldn't give up my Lyman manual. Where it's useful is for the data if you use RCBS bullets. It's worth having as a supplement to the Lyman manual but, somewhat limited on data and cartridges.
Overall it was a neat little manual.
