For the Ruger fans Pictures are HUGE so dont complain.
About 5/16" of gap from the bullet tip to the plastic of the mag liner
Same picture taken with one cartridge full aft and the other full forward.
Magazine in the normal position. The top edge of the metal portion of the mag to the vertical wall before the feed ramp starts is about .060
Same picture taken with the magazine in the downward position, like say if your hand was grasping the fore-end and came back to contact the mag. About .190 down or about .125 more vertical wall exposed. The truncated cone of the FMJ cartridge is not forgiving. Even the soft point super X's did it to some degree.
At this point the cartridge is free of the mag feed lips but not yet starting into the chamber, its free to flop around and this is where the bolt has about a 50% success rate with catching the cartridge and sending it forward. If it falls to one side or the other it will just jam up.
Here is a .308, the tip of the bullet is well into the chamber by the time the back end is free of the mag feed lips.
Same picture taken with .350, the tip of the bullet is just short of the chamber before the back end is free of the mag feed lips.
