From my research (after the fact unfortunately) it seems like the unique needs a little more than the nosler book says. It lists 3.3 as the max, but other books say different and from what I read, the max that the powder manufacure says is 4.6 grains.
I loaded up 10 rounds at 3.8 grains as opposed to 3.0 grains. I will give those a try and if those don't work, I will keep going up slowly until I find the point where the pistol cycles as long as it's under the 4.6 that unique lists.
Unfortunately I wasn't thinking ahead and loaded 100 .380 rounds with the 3.0 grain charge. So I got some work ahead of me to break those down and do them over once I find a good charge for my application.
