I don't think its a "good" thing in so much as was about the only way to get to the finish line. Now that people see the extraction system they've come up with... it opens the flood gates regarding the concept. I've never seen a rimmed extraction system like this before. Never talked to anyone that has. The extractor doesn't come all the way around the rim, it just barely comes past the apex of the arc the rim creates. Enough to grab it, but due to the fact there is only a few thousandths of an inch space between the front of the extractor and the breech face... there isn't enough room to put some kind of radius or angle on the front of it which would allow it to snap over a rim. Secondly, if it can snap over, then it can move... and if it can move, it won't be very good at extracting the round in comparison to a static. Think Mauser CRF action. They eventually figured out how to get one to single load and snap over... but they don't like it very much. In that instance, the case head on a centerfire is very thick, in comparison to a rimfire, leaving lots of room for an extractor to reach up over the rim on a centerfire.Is that a good thing? How it that beneficial?
So, because there is no room for any angle or radius on the front of the extractors, they can't easily be moved aside to get a round past them from straight on to the front.
What I will say unequivocally is that not requiring extractor cuts in the barrel is absolutely a good thing. It's an amazing thing. This means we can now do drop-in pre-fit barrels for a rimfire. Revolutionary. So the decision was clearly made that its much more important to not require extractor cuts in the barrel, than it is to be able to single load. A decision I wholly agree with.
It's a brand new never-before-seen system that is marvelous in its simplicity and reliability, but it does have that one singular drawback: You can't single load traditionally. Having said that, it would not be difficult to create a magazine or sled with a 1 round capacity that you could load one round at a time to feed up properly from beneath.
