Long ago in college I read Don Zutz Handloading for Hunters.
He talked about this very subject, and how twist was responsible for a Swede doing more radial damage than a 270 on deer.
The Good Old Swede by Robert Sherwood, 1970 Handloaders digest 5th edition. He test various twist Swedes for penetration and expansion.
10th Edition 1984 - Just one good bullet by Robert Masters, discusses the Swede/6.5-06, 264 WM and 6.5 RM and 125 Partition, deadly combo on deer thru elk.
Suffice to say, every deer I hit with a 6.5x55 dropped in its tracks. 120 corelokt and 130 NAB. It works
