Why I appreciate the Lee Enfield.

[Patrick Chadwick]

You are very likely right about the rimmed case rather than the action blocking gases,

It seems that some of you guys are still overlooking something basic about the Lee Enfield chamber, although Parashooter has already posted good photos to illustrate the feature. There is a gas vent on the left side, so that the action does NOT block gas in the event of a case rupture. That is why 5th Batt on the left was getting sharp puffs of "Enfield exhaust" !
