Abstract

Abstract A target has pairs of penetrable electrical conductive sheetlike elements that are flatwise opposed and spaced apart a distance to be transiently electrically connected by a penetrating projectile. Each pair corresponds to an annular scoring zone. Elements for radially outer scoring zones are on a permanent front sheet-like structure; those for inner ones are on a readily replaceable sheet-like structure installed behind the front one. To accommodate possible misalignment of the sheet-like structures the radially innermost elements on the front structure partially radially overlap the radially outermost ones on the rear one. Such overlapping elements cooperate for one scoring zone, and corresponding ones of them on the two structures are electrically interconnected.
