If the feeding is not truly controlled, then when the magazine releases the cartridge it will fall away from the bolt and into the chamber.
You know the reason for that, right? But just in case, that malady's cured via proper magazine spring tension; an issue I run into from time to time. It's a simple one to cure, via judicious altering of the angles in the bends in order to provide enough (and even) pressure on the follower..
If the feeding is truly controlled, by the time the magazine releases the cartridge it is already held by the extractor. You must try this with a full magazine, feeding with different tensions and from both sides.
Agreed..
Too bad you "avoided the push feed rifles", since many of those are excellent..
