I recently purchased a couple of 4 cavity mold from them. An ad in Handloader magazine is how I found them. I have been casting and shot them exclusively for over 40 years. These are the best and easiest to use molds I have ever had and used. The boolits come out of the mold .0005 oversize with my alloy and the weight varies 1.5 to 2 grains. I have used molds from most of the manufactures around and I feel Hardline is the best. Plus if you send them a couple of boolits they will make a mold to suit. I have talked to Derek and Mike at Hardline and they has always treated me like I was his only customer. They highly knowledgeable men and it is a pleasure to talk to them. I would recommend if you are in the market for a new mold you give them a try, I am positive you will be very happy.
