Be careful with 700x. It makes a nice plinking load in 38 special, .357 mag, 44 mag, etc., but a couple of tenths of a grain can get you over pressure in a heartbeat. I've found it to be very "spikey" and sensitive to very small increases in powder charge.
For this reason, I don't load it anywhere near the max charges listed for it in handgun cartridges.
