What's the original spec's on barrels???

The rate of twist is the same for cast or jacketed bullets. It's determined mostly by bullet length and velocity. The difference in a barrel optimized for one or the other is in the profile of the rifling itself.

It would be interesting to try a barrel sized to the ammo. I suspect that with a good bullet/barrel fit, a trigger job, and sights, the Luger would be a real tack driver.

Sieger and I have been working on some aspects of this. We still do not have a definite answer as to why the barrels are oversized. I have one explanation but at this stage it's shaky.

Some one gave me a theory on why today's ammo is too short. I'll have to run some calculations and see if it holds water.
