So both Yes and No, but mostly No. Anyhow the tale Ive read was that J. Browning had a hand in the overall workup of the system, the requirements being a cartridge ballistically compatible with the manstopping 45 Colt. Autoloaders were the cutting edge of the time. The cartridge was developed to fit in a magazine, but still be a manstopper. This required shortening the bullet to 230 gr. Supposedly they shortened the bullet to a specific length and this resulted in 230 gr, not the other way around. Physics today are the same as physics in 1908(+or- the year) so a short case and a short bullet can't equal a big case and a big bullet. Remember the 45 colt was the most powerful factory rendition until the 357 magnum was born. We won't mention the Walker Colt. Its only my 0.02$.
