For several reasons I thought I needed a 10mm lite a couple of years ago. One reason was an injured hand that did not take kindly to excessive recoil. I loaded 5.6 grains of W-W 231 behind an 180 grain JHP. Success! This was mild, accurate, and reliable.
I never throw away a loading manual. In Winchester's case this is extremely important, as they do like to discontinue powders. Found a can of W-W 540 just the other day.
As the chrono shows, 231 runs out of steam real quick. However, if maximum velocity is not required, it can still be a good choice.
The free world may be gross, vulgar and immoral, but that is not something that the slave society can fix.
