The container of claim 6 wherein the sum of the first end wall countersink distance and the second end wall countersink distance is greater than the tab height when the container is subjected to heating. 8. The container of claim 1 wherein the alignment feature is an annular rim. 9. The container of claim 8 further comprising: a flange coupled to the first end of the metal sidewall; anda seaming portion coupled to the first metal end wall;wherein the seam is a double seam formed by folding the seaming portion and the flange together, wherein the metal sidewall and the metal end wall have circular cross-sections, and further wherein the annular rim extends from the inner portion of the shoulder. 10. A metal container configured to be stacked on top of a second container, the container comprising: a metal body;a metal end wall coupled to the body by a seam, the end wall having a peripheral edge at which the metal body and the metal end wall are joined by the seam, wherein the seam includes a vertical inner portion, a vertical outer portion and a shoulder extending between the vertical inner portion and the vertical outer portion, wherein the shoulder is the lowermost portion of the seam;an alignment feature extending directly from the shoulder and away from the metal end wall;wherein, when the container is stacked on top of the second container, the alignment feature is adapted to interact with the second container to resist lateral movement of the container relative to the second container;wherein the metal end wall, the shoulder, the vertical inner portion of the seam, the vertical outer portion of the seam and the alignment feature are integrally formed from a single piece of metal material. 11. The container of claim 10 wherein the seam is a hermetic double seam coupling the end wall to the body. 12. The container of claim 11 wherein the shoulder is substantially horizontal shoulder and the alignment feature is positioned on a substantially horizontal shoulder. 13. The container of claim 10 wherein the vertical inner portion of the seam is in contact with the inner surface of the metal sidewall and the alignment feature is located between the innermost edge of the shoulder and the lowermost edge of the vertical inner portion of the seam. 14. The container of claim 10 wherein the seam includes an outer surface and the alignment feature is positioned on the outer surface. 15. A stack of metal containers comprising: a first metal container comprising: a metal body sidewall having a lower end;a metal end wall; anda hermetic double seam formed from and joining the metal end wall of the first container to the lower end of the metal body sidewall of first container; andan alignment feature extending directly from the hermetic double seam and integrally formed with the material of the metal end wall of the first metal container; anda second metal container comprising: a metal body sidewall having an upper end;a metal end wall; anda hermetic double seam formed from and joining the metal end wall of the second container to the upper end of the metal body sidewall of second container;wherein the first metal container is stacked on top of the second metal container;wherein the second container axially supports the weight of the first container via contact between the seam of the first container and the seam of the second container to provide a gap between the alignment feature and the metal end wall of the second container while the alignment feature prevents lateral movement between the containers. 16. The stack of containers of claim 15 wherein the alignment feature is an annular rim extending from the hermetic double seam of the first container. 17. The stack of containers of claim 15 wherein the alignment feature has an outer surface that is in contact with an inner surface of the hermetic double seam of the second container. 18.
