ONE 5.56 MM ELP LCS 44 GR. LONG COPPER SPIKE CARTRIDGE. HEADSTAMP WINCHESTER 223 REM. 44g. LCS (Long Copper Spike) projectile with both the effect of penetration and a Kit Tail. Because of specialized Product Engineering this projectile for a little longer shots, yet still separates on solid impact like its Brass brother launching the core for only the effect that self lubricating Bronze/BRASS can give to control those Varmints and Predator hiding in the out buildings on the ranch.
