Loading 40-70-320 anyone have safe load for Unique? I use 12 grains for 40-65-250. Thanks Bill
Bill,
I strongly would not recommend using Unique powder in that cartridge. Instead, load it with 24 grains of 4198.

I loaded the 40-70 with 5744, no one had info on Unique..Bill
It’s quite possible to work up safely from 8 grains of Unique with a half sheet of toilet paper as a spacer. I’m a big fan of 5744 for similar cartridges but it’s so dirty and stubborn to clean I’m beginning to see the light and dabbling with Bert’s favorite, 4198.
