Ross,
The 2 La's I acquired averaged just that amount. I was envisioning a real dog of a piece.
The chamber's rearmost rim is quite sharp on these, and I think it helps to break and smooth it a little, particularly at the top, by the extractor cut, where it's like a gouge. The noses of slightly errant rounds sometimes catch on this, and if the round doesn't wedge itself in the action once the tip is caught, it will shave off little crescents of lead as the round goes by into the chamber. I'd noticed quite a pile of these on the floor of the action after coaxing a handful of mags through it.
This evening I've corresponded with the seller of a La22 mag I bought. He used to work for the importer and has more parts available for me in a week or two, including--now, get this--a factory magazine alignment mandrel! I'd begun to fabricate one myself, but this will save a lot of effort, and perhaps yield better results. So, don't scrap that mag if it's a bummer; it looks like I'd be able to deal with it after I score this tool.
