I just got my new Star Magma sizer and told them I was going to start out with 45acp boolits with 1 lube groove. They would send a die accordingly. The die they sent has 2 sets of lube holes. The instructions say to plug one set. I ordered a die from lathesmithe for the same so I could try out his dies. Will his die have 1 set of lube holes or 2 like the Star die? I am going to wait on his die before I set up and use this sizer. I also have a Lee 45 250 gr mold which has 2 lube grooves I just bought. I havent measured the lube grooves yet, but I hope I can use this for these.
