By surprisingly popular demand, here's a video about primary extraction, which is how a sticky case is shaken loose from the chamber after firing.
Featuring an M1 Garand, which has (almost?) no primary extraction, a Mauser Kar98k which has the most common type of cam-based extraction, a Lee-Enfield No.4 (NOT an SMLE), and a Swiss Schmidt-Rubin K31. The last of these is a straight-pull with a really, crazy powerful primary extraction based on helical locking lugs.
For the observant, this video is actually also a stealth Lee-Enfield No.4 vs. Mauser 98k video :D

By surprisingly popular demand, a look at The Bloke's shooting jacket, and how to use a side-mounted sling such as on a Swiss Schmidt-Rubin K31, K11, Mauser Kar98k or whatever. Also includes a brief digression into why you should not attempt to free-float a rifle like a K31 (or a Lee-Enfield No.4).
