Never tried Hodgdon 700x, but have had a lot of luck with IMR 700X. Let's not forget it isn't a Hodgdon powder, its a DuPont powder, and Hodgodn, let's not forget who cut the beloved SR line, have shamelessly scrubbed the real name and glued their own on it. I don't like the people who run it, not one tiny bit.
In any case, I've had very good luck with IMR 700-x with light target loads in 38 Special, especially with 195 grain Lyman bullets, got a low velocity and very accurate target load out of it using 2.4 grains. As said, metering is an issue, so I don't use it in my progressive, and tend to go back to Bullseye anyways, but it certainly is a viable choice for light loads.
Speaking of skeet loads, IMR 700-X is the go to powder for my 10 gauge 15 pellet 00buckshot loads, works flawlessly, and I just hand scoop and weigh those charges and forgo the whole auto metering for IMR's Hi Skor 700-X.
