More importantly, by the time the feed ramp forces it to nose up, the angle of entry into the chamber is more acute. If the ramp is a half-degree too steep, there’s a good chance that it’ll stop or drive the bullet back into the case…even if it does feed. The tapered lips let the front of the round “nose up” while the parallel lips maintain the straight shot into the ramp. In this sequence, we have cartridges in both magazines at approximately the point of feed ramp contact, as the ramp works to guide the round toward the chamber. Here, the rise of the rear of the cartridge is in evidence. There is one cartridge sitting on the follower in both…pushed forward to just before the release point with the rim caught on the dimple, but not simulating the upward angle imposed by the feed ramp. A picture is…they say…worth a thousand words.įirst, we have a “Hybrid” magazine compared to a 7-round “Wadcutter” magazine of unknown manufacture. In my replies to this thread, there are pictures illustrating the different feeding characteristics between a USGI magazine, and a typical aftermarket “Wadcutter” magazine. This does happen, but it doesn’t have to be rule.Īssuming that the feed and barrel ramps are properly to spec…and assuming a magazine that is suited to the cartridge overall length is used…one round can be chambered 12-15 times with no more than. Taking a little side trip before proceeding…much has been made of bullet “Setback” after chambering the same round 2-3 times…and it can happen on the first trip. On a feed ramp out of spec in the other direction…less acute…it combines with the rear of the round moving up in the taper and gives the cartridge a better chance of gliding over the top corner of the barrel ramp instead of forcing it straight into it. This makes a feed ramp that’s been cut a little out of spec (acute) less critical. They let the rear of the cartridge rise at a predetermined rate as the round moves forward, maintaining a less severe angle as the round enters the chamber…but it also does something even more important.Īs it moves forward into the increasing distance between feed lips…when the bullet nose reaches the feed ramp, it allows the front of the cartridge to more easily angle upward. Enter the tapered lips and the late/gradual release of the “Hybrid” and the original “Hardball” type magazine. If the angle is too steep…too acute…the bullet nose can’t glance off and angle upward. While the magazine is most often the root cause, sometimes it’s the feed ramp geometry itself. His trouble started with “Nose-Dive” misfeeds with the feed ramp stopping the bullet’s progress to the chamber. Not a cure, but a dramatic difference all the same.
