    You're going to need a sizing die of the proper diameter and a top punch. For nose first sizing, you'll need the flat punch. I'd suggest getting those from Lathesmith here on this forum, as his quality is first rate and the prices are more than reasonable.

    If you're going to use a soft lube, you won't need a heater, but if using a hard lube, then a heater will be necessary. To start, you won't need an air piston or bullet feeder, but may want to add those later on. I've never really found the need for the air feed on my machines, but I can see where it could be a good addition. The bullet feeder is an individual choice. On some bullets that are easy to grasp, I can feed them into the sizer at a rate that nullifies the time it takes to fill tubes for the bullet feeder. Other bullets, that are hard to grasp, benefit from being tubed and fed through the bullet feeders. I have machines set up for both.

    That's enough to get you started, but you should go to Magma's website and download the manual for the Star Sizer, since it has a lot of information in it and will tell you how to set up your dies to get the lube in the lube grooves, instead of on the nose or base...... Here's their link:

    Hope this helps.

    After getting the download, start keeping records of how far down into the sizer die the base of the specific boolits desired to be sized needs to be in order to align with the hole(s in the case of double lube groove boolits). You will need a measuring caliper for that in case you do not yet have one. A couple of days ago I had a difficult time getting a Lee 2-groove boolit lined up properly. I checked my records and they indicated the boolit base should be .800" down into the sizer die. Fooled with it two evenings before I finally pulled the die out, scraped off the lube, and held the boolit next to the holes in the sizing die and measured to the top of the die. Base of the boolit needed to be .700 down from the top of the sizing die. I had previously only lubed the lowest groove toward the base, then decided I needed to lube both lube grooves. When I did that I opened the next set of holes and moved the boolit upward ... but forgot to record that in my notes. Save yourself a lot of fumbling and fuming by measuring the distance from the base of the boolit [with the open hole(s) lined up with the hole(s) in the sizing die] to the top of the sizer die and record that.
