Sorry, I know this is a really long shot but have not had any results in repeated internet searches.
First off, I DON'T and will not do Tumble lube, so that is not even a question or option!
I have and use, successfully, two sizer and lubers - one each RCBS and Lyman.
However, with 175gr 30 caliber cast bullets, I am having a problem maintaining concentric bullets. Meaning some go through removing all or most of the lube grooves from one side of these small dia. bullets.
My top punch should be just fine, however ------------
When I found this small Lewiston, Idaho machine shop, I wrote down the info and then sent them an "E" to which they have NOT responded. Problem, I must have thrown away the written info and now have not again been able to find the company on line.
This machine shop made a custom nose first sizer and luber that looked like it might do the job, but alas I can't find them.
I live close enough that I could go to their shop to have a hands on look at their tool.
I first found the info when I was looking up info on the Star luber/sizer.
Star is not really an option as I have too much invested in my current tools and all the dies, so I was and am looking for another option to solve my lop sided 30 caliber bullet situation.
Thanks for any help you folks may be able to provide.
