I tried a new- to- me method of seating gas checks today, that seems to work well on flat nosed bullets. This idea is probably not original, and I may have read about it somewhere, I can´t remember. Anyway, it was useful to me and it might possibly be of use for someone else, so here we go:
Mount a Lee sizer in your press (doesn´t matter what caliber it is), and introduce the corresponding push rod into the sizer (without fastening it in the ram). The push rod will probably stay inside the sizer, if not you can retain it with a glob of alox). Then, put another push rod in the ram (of the same, or larger caliber than the bullets you work with). You now basically have a «gas check seating die», where the base of the upper push rod acts as a «top punch». I honed the base of mine slightly, as there were small imprints of machining marks.
This principle will probably also work on pointed or RN bullets, if you have the NOE bushing- sizer with top punch holder for the ram, allowing base- first sizing. Will try that when the next goodie-box from NOE arrives
