That was a good one, too.

I don't dis-believe in OSR, but I have yet to be shown the actual mechanism that causes it. By that I don't mean "hard bullets", I mean how a "brass bullet" actually passes the length of a barrel causing the lands to impress outward evenly and produce the "swirl effect" on the outside.

I did contact Barnes and I forget all the but IIRC, they were willing to test the theory on a barrel turned to "double" diameter.

BUT AS FAR AS I KNOW, THEY NEVER DID IT.
