Thats correct. The STW is smaller than the Scramjet. And if any brass on earth could be pushed in pressure, it's Lazzeroni brass.
QL shows the scramjet as having more capacity(2.5gr more), however I drew up both quick in RCBS load, and it looks more like 5gr to me. Now this assumes that the STW was simply necked down and not improved. The SJ I was building was 40deg at the shoulder, w/less body taper(like the Banshee), and nothing out there would have touched it.
In fact, the rifle is still being built by PGW. But I've decided not to use it(will sell).
The 257WBY is a full 20gr below the Scramjet.
Here's a pic comparing the two cases:
