Everybody does seem to get their panties all in a wad over this, but many don't realize such contact will occur in a mid-spec Government Model. My wadcutter gun has 10's of thousands of rounds through it with such contact and resulting case dents and it doesn't bother me, the gun or the ammunition at all. Gun's had the same extractor since the early 1960's. Extractor's still OK and the dents in the case extraction groove don't affect a thing - I reload them until I lose them.
When I test the extractor to see if it grips the round properly, the round is perfectly level as I do this.
Are you guys saying that if the round is at a slight angle, it makes it easier for the round to position itself properly with the extractor.
Not me. If you think about how the case rim gets up into contact with the extractor nose, the case angle is essentially fixed by the design of the gun and there's little or nothing that can be done to change it.
I don't see what the problem would be, if the horizontal round slipped into the extractor, but I can understand this part of the write-up.
If you'll look at 4:32 of the video you'll see that if the round is horizontal it is already under the control of the extractor (or if not is getting in the process of being push fed).
I think this is what is happening when my short Magnus #801 bullets go into the barrel of my Baer Premiere II. I'm guessing that the write-up is saying that the bullet needs to contact the chamber further away, rather than closer. Is this ti keep the cartridge at the correct angle, so it doesn't "jam up" and lock in place? Just guessing, but that's what I think the article is saying...
I don't understand what the article is saying either unless the writer is hypothesizing why SWCs can be hard to feed.
Most of the jams I got were with rounds at the lower part of the magazine, but when I tested this in my apartment, with dummy rounds, all of the Magnus #801 rounds locked up. It didn't matter where they were in the magazine. I am looking at my magazines from Springfield, Baer, and Wilson. None of them have anything that looks like a tiny little bump.
That little bump is part of an Ordnance spec'd magazine follower.
I'm lost here. No idea what this is describing.
Why would the extractor be snapping over the rim? I assume the rim is pushed up against the extractor, just like when I did this by hand, and the rim just naturally goes "into" the opening in the extractor. I can't visualize what is being described here.
What's being described is a push feed, a situation where the case rim gets ahead of the extractor instead of sliding up along the breechface. The forward moving slide and extractor will chamber the round and then the inertia of the slide will cause the extractor claw to snap over the case rim. Many claim push feeds will bring about an Earth-ending apocalypse but fail to realize many guns push feed and the shooter never knows it: the gun goes BANG!; the brass is never examined or even if it's reloaded, the little marks left by the push feed on the case rim are never noticed (they don't affect reloading at all).
One important false impression left by the video is that all cartridges from the magazine feed the same way - specifically their attitude (angle) when making first contact with the frame feed ramp or the barrel ramp.
• The first round out of any full magazine will make first contact down the lowest on the frame feed ramp
• The last round out of any magazine may not even hit the frame feed ramp - and strike only the barrel ramp.

So your gun jams, huh? Try this little experiment based solely on a hunch of mine:
• Assemble your Les Baer without its firing pin and lock its slide back
• Measure and record the overall length (COAL) of one of your reloads.
• Load this as the top round in a full magazine.
• Insert this magazine and slingshot the slide closed.
• Carefully pull back the slide with the gun on its right side and extract that unfired round into a rag
• Re-measure the COAL of that extracted round and a find out how much shorter it got just from chambering
Q: How much shorter did it get?
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. [Lord Kelvin]
