A weapon system, comprising: a firearm having a barrel defining a bore extending from a rearward end toward a forward end, wherein said firearm includes a bolt having a forward face adjacent said rearward end of said barrel, said firearm further including an extractor; a cartridge in said bore of said barrel adjacent said rearward end of said barrel, said cartridge including: a case for containing a propellant, said case further defining a pocket extending forwardly from a rearward end of said case to an end adjacent said propellant; a projectile at a forward end of said case; a primer-supporting member in said pocket adjacent said rearward end of said case; and a primer in said pocket between said primer-supporting member and said propellant, wherein said primer is positioned entirely forwardly of said rearward end of said barrel; wherein said extractor is engaged to a rim of said cartridge at said rearward end of said case and said extractor is reciprocal relative to said bolt such that when said bolt recoils upon firing of said cartridge said extractor remains motionless relative to said case while said primer and said primer-supporting member drive said bolt rearward until said bolt engages said extractor to displace said extractor rearwardly and withdraw said case from said bore in said barrel.
