I recall an article that discussed crimping and bullet fit in handgun cartridges. Scovil did comparison tests evaluating tightness of bullet fit, versus crimping, and the effects on accuracy and velocity variation. His results showed that a tight bullet fit, combined with a firm crimp gave the best accuracy and least velocity variation in the .45 Colt, and a firm crimp alone did not provide the same benefit.

That was probably one of the top 5 handloading articles I've ever read, anywhere. I used the same approach going forward for my loads, and I benefited a lot.

IIRC Scovil also worked with Turnbull on the development of the .475 & .470 Turnbull cartridges. I eventually wound up with a .475 Turnbull #1, and it is my rarest and most accurate big bore Ruger smile

I have always enjoyed reading Scovill. The O'Conner sidetrack seemed a bit odd, and I rarely enjoy anyone's writing about cast bullets or black powder, but enjoyed reading him first all the same.
