It doesn't surprise me a bit. My first DE was a 44 Magnum I bought when they first came out around 1987. That POS had all sorts of problems and hit about 12" high at 50 feet. Even at 100 yards, it was WAY over the target.
I ended up machining the rear sight down to the point the notch was nearly gone and then had to recut the notch nearly down into the base. I also bought a complete 440 Corbon gun when those came out in 1997 or so. It didn't have any sight problems but ejection was rather wild to say the least.
Back in 1999-2001 we made about a dozen AR-15 uppers in 440 Corbon and I still have the chamber reamer and head space gauges. I dropped the 440 Go-Gauge into the 429DE barrel and the bolt won't close on it, nor will it chamber 440 Corbon ammo. I appears though, that a 429DE round would chamber in a 440 Corbon barrel, but of course you would most likely have excessive head space.
