Greetings All,
Does anyone have experience in modifying one of the Lee Push Through Sizing dies to increase the diameter? I am looking at making a sizer for my 470 Nitro Express cast bullets that will be powder coated. I need to size them to 0.476 and was thinking I could use the Lee 0.452 sizer to enlarge the opening. I suspect the best way would be with a lathe but perhaps it could be opened from 0.452 to 0.476 or 0.024" with an appropriately sized mandrel and fine sandpaper or valve grinding compound on a drill press. I think the "push stem" might still work as supplied with the sizing kit but not sure until I try it.
Anyone have any thoughts on customizing one of these dies.
Thanks for any insight.
Paul
