The rounded nose on this pattern indicates it is case-shot. Please note the
original papier-mâché' sabot on this non-excavated example. The lower zinc band, which
helped decrease humidity-related swelling, is missing. Since the papier-mâché'
sabot fit
so tightly in the bore, no flame could pass to light the conventional time
fuze. A
self-igniting fuze was used in an attempt to correct this problem. However, the
combination fuze worked very poorly with only approximately a 55% success rate. This shell
has seven raised ribs on the tapered cone. Go

combination fuze and click here for a cross-section of a 3-inch Schenkl case shot
projectile.
