The 225 brass inspired JD Jones to use it in his cartridges. He's a smart cookie and has demonstrated his skills.
It has thicker brass walls, not only for JDJ cartridges, but for those who still shoot the 225. With a minimum of care, they can last longer.
In tandem with the above, they work marvelously in single shots because of their strength, thicker brass and rim.
The last reason is that they simply look cool.
In Star Wars, when Obi Wan was "killed" by Darth Vader, Obi-Wan came back stronger than ever.
That is hardly earth shaking change the world type stuff. The thing that JD had that was ground breaking is that he started working with a man named Jurass who had been playing with jacketed HP bullets in the 357 mag. Teamed up with JD they made the first ever 110 JHP +P ammunition for the 357 mag and later 38 special +P and 45 acp + P which was marketed to police departments around the US under the Super Vel name in 1967 which indeed did shake up the world. This however had nothing to do with the 225. Super Vel went under in 71 or 72 at which time Jurass went back to working with JD on high performance hunting rounds for Thompson Contenders and SSK industries was born.
Absolutely nothing groundbreaking or Earth stand still came from the 225 Winchester.
