  Tubes and primers for ammunition - Wikipedia, the free encyclopedia
If friction tubes are employed when cordite or other smokeless powder charges are used, the erosion of the vent is very rapid unless the escape of the gas is prevented; in this case T-headed tubes are used.
The force of the explosion expands the tube against the walls of its chamber, while the internal structure of the tube renders it gas-tight, any escape of gas through the vent being thus prevented.
For larger guns an electric primer is used, the internal construction and action of which are precisely similar to the wireless tube already described; the exterior is screwed for the case.

Since their introduction, lead free primers have improved to the point that they are nearly equal in performance to lead based primers, and will likely become the norm in the near future.
