I have some questions for everyone else making cartridge pens.
I turn the base of the upper barrel to match the top of the 308. I work carefully to follow the 308's form and fit 'em tightly.
So, one of the finished pens looked good until I rotated the barrel too much while closing the pen and got it out of alignment?!? What I found is that the cartridge wasn't round and I had turned the lower end of the upper barrel to match it.
Okay, I rotated it back and sure enough everything lines up. That is, of course, until the pen is opened again.
It's out of round enough that I'm surprised I didn't notice the shape while working it.
Questions thus:
1. Do y'all check the cartridge for roundness before using it?
2. If it's not round, do you try to make it so and is there really a way to do that accurately?
3. If ya don't worry about round, would you follow the non-round shape when making the upper barrel?
4. If you answer yes to #3, do you match things up when open or closed?
5. If you think these questions are anal, please go back to #1 and start over. [}]
After making some 308's from Gary Max, a friend saw them and gave me a bunch of 30-06's. This is the first time I've experienced an out of round cartridge.
