@MER, there are several nasty areas which need special attention. Perhaps, this bunker is one of them(?)
In general, my rule of thumb for 30/40 bunkers is,
- take a wedge (PW), and
- don't expect more than 70 yds.
From 20/25 sand, any iron punch might show good results, and from 50+ bunkers, swallow the pill and be happy to get out.
