One of my favorite loads is 1-1/8 oz WC 8's, CB or DR wad, W209 primer. I use 17 grains on the nose, which splits the 1150 and 1200 fps recipe, figuring it is around 1175. Never chrono'd it, don't have one. But it would appear to be a very safe load, fairly low pressure. I prefer DR wads, but with 700X being so dense, the crimps are better on CB. Solved that issue by using Clays.
While there is published data on 1250 fps load (19 grains), the pressure was 11,400, and that just seemed on the edge. With so many slower powders, I saw no reason to press my luck. I have GD and Unique for anything faster. I am relatively new, and shot little handicap, so for my game so far the above load has been fine. I have a jug of GD and Unique both when I push back further.
After watching Ron Alacoriza shoot from the 27 using light Estate 8's, not sure a turbo load is necessary, but I don't have the experience or ability of Ron, never will.
My MEC 9000H throws a little heavy so to get 17.5 (really 17.2 +\- a few tenths) I had to back off to a #28 bushing. A #29 bushing was throwing about 18.1 to 18.3 grains and that was a little more than I wanted.

17.2 gr 700X
Ounce and an eigth of 7.5
I find it's a nice, consistent load, clean burning even when chilly (< 40 degrees).
Jay, while the 29 bushing may work for some loads, the 1150 fps loads for most wads for both those hulls with 700X powder are 16.5 grains. This powder weight needs to be weighted to verify what your machine is actually droping?? You may need a 28 bushing??? You will need to buy a scale to weight your charges??? You should also go to hodgdonpowder.com to find your load with the wad and speed you want to use. Try not to go over 10,000 psi chamber pressures when you find the load and speed you want with the components you want to use. You may want to find a different wad or change one of your components to lower the chamber pressure to suit your needs or wants. If you have any questions let us know and we can help stear you in the right direction. Best of Luck and Break-em all. Jeff
Use a scale, verify your drops, and double check your data. Anything over 10,000 PSI is too high for my liking. I like to have a little headroom for error. Assembling loads at the max does no favors to your firearm and serves no real purpose. I go for aroung 9000 - 9500 PSI (NOT Lups). LUPs is a different animal. Don't EVER believe a bushing A will give the same drops in Machine B with different lots of powder and different operators. You might get lucky and then again, you might get VERY unlucky.
You need to check every lot of powder you get. Each one can and often will drop differently. The last canister of 700X I bought drops very heavy. I am using a bushing that last time dropped 16.0 that now drops 17.4. I have double checked several other bushings and each one dropped heavy. Check each lot just for your safety.
Some may disagree, but go with a Universal Charge Bar and be done with bushings. I can fine tune all of my powder and shot drops. I can adjust and drop powder to the exact grain that I want and +/- 6 pellets with the shot.
I am looking at 700x just because it seems to be the cheapest powder right now.
