700-X works well with cast, plated, and jacketed 230 grain RN bullets. With the load I use, all three shoot with the same nominal velocity, 810-820 fps, and to the same point of aim.
I have probably loaded 700-X with other shaped bullets, but 230 RN is pretty much all that I have loaded in 20-25 years.
As far as metering, it meters about the same as Unique. No problems with and RCBS Little Dandy measure or a Redding 10-X. I did have some issues with the Hornady L-N-L on the Hornady progressive. But, I bought a Dillon SDB to try and it is dedicated to 45 ACP. The Dillon powder measure meters 700-X just fine.
Unique meters just fine for me as well.
I recently tried some 700-X in the 44 Special and liked that load. The 44 Special is loaded on the Hornady progressive with a case activated Redding 10-X powder measure.
There are other powders that work just fine in the 45 ACP but 700-X works for me.
