No help with the 700-X, but I find that 4.5 grains Green Dot under a 200 grain lead semi-wadcutter in .45 ACP is a mild load that prints well and does cycle the action of my 1911.
Also, for "light" magnum loads in .357 mag for short barreled revolvers, 6.5 grains Green Dot and a 125 grain jacketed bullet give me about the same velocity (1150 fps) as factory rounds (Remington Golden Saber - a mild load for a factory load) in the short barrel, without the shock, noise, and drama. A similar load might work in .38 special, but it would be worth checking and starting significantly lower.
http://www.alliantpowder.com/" onclick="window.open(this.href);return false; has load data but none for Green Dot in these calibers. The ones I mentioned are from an old hardcopy booklet from Alliant from years ago.
