I have one of his seaters and as long as you have the correct top punch it seats them perfect and square every time.
Neat tool for the job!

This is how I do it. NOE top punch holder in the ram (it comes with his push-through sizer), with a suitable top puch. Then I mount a Lee push-trough sizer in the press, with the appropriate push rod stuck in the sizer (retained with a glob of Alox). The base of the push rod then acts as an anvil, against which the gas check is squeezed. Not a good solution if there is a genuine mismatch between check and shank, but helpful in many cases.

Like Brad I dry size to seat the check then coat and then I do my final sizing.
usually I try to use a push thru that does not touch the bullet just crimps the check slightly so it does not fall off. I tend to get better coating results if the bullet has the matte finish instead of the shiny finish.

Didn't say it was broken, but following the sequence through several different individual's methods I come up with some confusion. Coating before applying checks makes it difficult to apply checks to now oversized shank. Reason for not applying check first is perceived need for lube and subsequent lube removal (or) sizing before coating makes slick bands and powder may not coat as well. Hmmm.
I have none of these problems, actual or perceived because I apply checks before coating, lightly pre-size without any lube (either just to crimp the check securely as Max mentioned or with a tighter die to reduce the whole bearing surface diameter slightly depending on cast size vs desired final size), and shake the bejeebers out of them with the BBs to ablate the oxides off the bullet surface and get a really nice embedded coat of paint on them. I.e. it makes me feel better and I know the substrate is roughened and oxides blasted off by the aggressive shaking action and the abrasive powder, and the bullets are otherwise unharmed.
That said, the gas checks are pretty slick and the powder adheres to them extremely well. Also, powder that is ES sprayed onto bullets that have been pre-sized adheres extremely well, so really it is only a matter of preference what we do; the stuff will stick.
I thought that dry-sizing checked bullets would wear out a sizing die, and eventually it might, but several thousand bullets through my .309" and .451" Lee dies haven't changed the dimensions yet, so I'm not worried about it.

I use a Lee type push thru for much of that kind of sizing these days. It can lead but I haven’t had too much trouble except when I sized down pure lead 457122 HPs to .452 for use in ML sabots.
The Star doesn’t get used because without lube the effort exceeds what I am comfortable with. The loading press doesn’t even break a sweat.

The next size up from the 0.356" final size die I have is 0.358" These bullets come out at 0.359"-0.360". So all the bands are nice and shiny even going through the 0.358 sizer. The checks seat with just a little tap after PC them. But not always. I would rather use the die that NOE makes to make sure they are all seated all the way.
I am going to order it anyway and see. I can always use it for other molds.

I've tried seating gas check on coated bullet a couple different ways and found it just easier to apply the checks before coating and do final sizing after coating the bullets. It's just less frustration trying to get the check onto the bullets base more than anything and the coating also helps bond the check to the bullet.
