Sizer punches for both Star and Saeco are a problem because they use a bastard thread which I, or no one I know of can duplicate. I understand that Saeco can supply an adapter to handle RCBS and Lyman sizing punches. Check with them about this, and if so I can make a fitted punch that will work fine. The other option is to purchase the largest punch Saeco offers in the caliber you want to order an LBT mold for, and fill it with epoxy, which is then set over the bullet. This will never deform a bullet, or wear.
For Star owners who have the same question, only flat punches are needed, and they should be about .010 smaller than sizer diameter for gas checked bullets. Gas checked bullets should be pushed through nose first, so the punch can press the check base flat against the bullet and hold it there during sizing. It is the best sizing arrangement there is for gas checked bullets. For plain base or bevel based, push the bullets through base first, using the same punch. In other words, Magma supplies suitable punches for their Star sizers, for any caliber they offer sizer dies for.
