Borchardt-Luger Controversy

Unspellable,

Thanks -- I'm grateful to be corrected and remember your excellent test series.

By construction the ear won't let the tip of the firing pin protrude from the recessed part of the breech face until the breech is within about 0.050-inch of closure (easy to check this by measurement). So no matter what the release point was, the actual instant of your test primer ignitions must have occurred somewhere between 0.050 in. open and locked. I thought the amount of cartridge casing exposed at ignition would affect the degree of danger to the user (less being better), but maybe I'm wrong. I don't think any of us wants to do the test series that would tie that one down!

I certainly don't dispute the fact that a blowback accident could happen, as the last sentence of the first paragraph of my previous (08-22) post said.
