'Unique' powder claims to be one of the most versatile powders there is, I would agree. I've used it in the following calibers:- 45/70, .308, 7.5/55, .303, .223, and 6.5/55.
About 7 grains in a lightweight .223 round will give a nice light load. 10-12 grains in .308, 7.5/55 or .303 will send a 100 grain bullet out OK, and 13-16 grains in 45/70 behind a 410 grain bullet.
All of these loads give a nice easy crack, and a reasonable velocity. Longer range accuracy is a bit dependent upon the rifle / bullet combination. The best load I has was from a 7.5/55 using Hornady 100 grain bullets (can't remember the name of the bullets, they were lead, with what looked like a large gas check on the back half) They were shooting an easy inch at 50 yards. A good fun plinking round.
Some people may worry about flashover with such a light load. This is a problem when using slower powders to load below minumum recommended loads. Unique is fast enough that this won't happen. The only problem with is is, as far as I can see, that your metering has to be spot on with such small amounts, as even a small variation can be a significant percentage.
Good for those ancient military rifles that you don't want to overstress. The recoil is negligible too. Ideal for a day's plinking.
