The assembly of claim 4, where the aperture extends at least about 5% of a diameter of an inside surface of the casing. 6. The assembly of claim 4, where the first explosive charge and the second explosive charge contact at the aperture. 7. The assembly of claim 1, wherein at least one of the first liner or the second liner comprise an opening around a skirt. 8. The assembly of claim 1, further comprising: a third liner;a third explosive charge disposed between the second liner and the third liner; andwherein the first, second, and third liners are collapsible to provide a stream of particles that form a single jet upon detonation of the first, second, and third explosive charges. 9. The assembly of claim 1, wherein a portion of the second liner extends towards the first liner. 10. The assembly of claim 9, wherein the second liner contacts the first liner. 11. The assembly of claim 1, further comprising an aperture disposed through the second liner and the second explosive charge. 12. The assembly of claim 1, further comprising a detonator cord coupled to and configured to detonate the booster charge. 13. The assembly of claim 1, wherein the casing comprises a cylindrical shaped portion and a frusto-conical shaped portion with the booster charge positioned within the frusto-conical shaped portion.
