Nonte in "The Home Guide To Cartridge Conversions" shows 3.5 grains of Unique with a 100 grain, .325" lead bullet.
Some research I did on the web(I don't recall the web site) gave a load of 4.0 grains of Unique with a 100 grain, .330" Graf's FMJ bullet.
The same web page listed 2.8 to 3.2 grains of Bullseye with the 100 grain .330" Graf's FMJ bullet.
Using a Lyman #32359 .325" 121 grain lead bullet, they also listed 2.3 to 2.5 grains of Bullseye.
I have not used this web data and cannot verify its validity. I personally load slightly less than Nonte's data.
