Huskqvarna 46: I'm forming my cases from PPU 8mm brass right now without problems. It would be good to have some trim to length data. There's a case length in the diagram. I was looking for real world numbers.
Also, have you found the groove diameter to be potentially problematic as in oversized. Is there anything odd or unusual that may be a concern.
Added: The Hornady dies are working very well. They're worth a look.
So here's what I would do as far as case length . I'd grab an 06' out of the orphan mismatched range brass bucket and size it without the expander until I had a firm bolt closure then I'd over anneal it . The quality doesn't matter here you want it to move easy and fully imprint everything . Then prime and charge it 5-7 gr of Unique or something between it and Red Dot . Fill the case with Grits , corn meal or Cream of Wheat . Add an appropriate plug of wax or like to keep the cereal and powder in the case an layered . It'll be pretty load when you fire it and at 10' the Grits will still saw right through a cardboard box . Inside you will have a line where the end of the actual chamber and a pretty good look at the throat and leade . Trim to the line and another .001 , adjust as needed for actual fired loads .Originally Posted by Mowgli Terry
I've been surprised more than once by how much longer the neck in an actual chamber was than the specification and once by one that was just literally a hairs breadth longer than standard trim length .
