No. I don’t like inaccuracies that make B movies look like gospel truth.
Depends on if you had a pre-64, post-64 push-feed, post-64 controlled feed, or post-64 control-round push feed.
Actually, it only matters if it was pre or post ‘64.
Pre-64’s extractor often either won’t snap over the case-rim and therefore won’t allow the bolt to close, it often also bends the extractor in the purpose requiring replacement (which is a simple ~30 sec fix.). In the event of a “non-snap-over” you’ll likely end up w/a bolt you have to hammer open, when it lets go you’ll have a projectile stuck in the lands and an action full of loose powder.
The newer control round feed “classic” actions have an extractor that’s beveled to snap over w/out being fed from the belly. But, a bit of condensation and a re-freeze can negate the bevel, disallow a “snap-over”, and you’re back to hammering the bolt open, flinging loose powder, and a bullet stuck in the lands.
Push-feed and control-round push-feed will feed loose off the magazine follower (without being snapped into the mag-box) without a problem.
