Analysis of elemental and isotopic variation in glass frictionators from 0.22 rimfire primers

•Glass frictionator present in 0.22 rimfire primers can be detected in GSR.•Elemental variations in the glass can be exploited for GSR case investigations.•A inter-brand discrimination power of over 90% has been calculated using ToF-SIMS. The majority of 0.22 calibre rimfire ammunition available in...
