Does anybody have a good load for this bullet with Unique?

There are several obstacles I'm facing:

Berry's doesn't publish load data
Berry's suggests at LEAST 800fps for these plated DEWC
The only data I have found suggests a max load of 3.3gr Unique with 148gr with a velocity of 750-800fps
My AutoDisk powder measure is not consistent throwing charges of Unique less than 4gr

I loaded about 50 rounds this afternoon and had to weigh every charge because some would come in at 1.5 randomly. I'm going to de-static the hopper and make a powder baffle to try to prevent bridging to increase the consistency of my throws. That said, it would be nice if I could get some confirmation that it is okay to load these in more of the 4.2-4.5gr range.

I think it should be fine considering that 158gr LSWC loads show a max charge of 4.7gr per Alliant's website and (generally speaking) it is safe to use lighter bullets at the heavier load data. The argument against that is that the DEWC has more surface area that contacts the bore and therefore will increase pressure.

I'd rather not change powders or buy new equipment.
