An oil and gas well shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (), a high explosive (), and a reactive liner () where the high explosive is positioned between the reactive liner and the housing. The reactive liner () is produced from a reactive composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition is a pressed i.e. compacted particulate composition comprising at least two metals, wherein one of the metals is present as spherical particulate, and the other metal is present as a non-spherical particulate. There may also be at least one further metal, which is not capable of an exothermic reaction with the reactive composition, present in an amount greater than 10% w/w of the liner. To aid consolidation a binder may also be added.
