Anybody load 10mm? Got a few questions

[Dirtshooter]

Hi guys, I have been loading 10mm for awhile using 800-x powder, but recently got some AA#7 to load some .357 and saw some load data for 10mm. The question I have is my Speer #12 manual lists AA#7 11.0 gr start with a 1065FPS, 12.0 max at 1180FPS using 180 gold dot bullet. The test gun was a 5" S&W 1006 pistol according to book. So I load up several rounds using 11.0-12.0 in .2gr increments and head to the chronograph. Only difference I used 180 gr Hornady XTP bullets and fired from a S&W 610 revolver 3.875 and shooting the start load of 11.0 I fired 3 shots 1266, 1275, 1260FPS. The primers looked ok, but I quit shooting because my speed was close to 80FPS over what they showed with a 12.0 max load. Anyone have any data or has shot this load? I am developing this as a deer round in case I get one into bow range. Thanks for any info, I have searched quite a bit on the net. I would rather not blow up my 610 and prefer leaving the range with all the fingers and toes I came there with.

This is from my 2011 Lee 2nd edition manual.

Thanks Bill, I am very cautious about reloading and don't believe anything I hear and not much I see. As evidence of what my Speer manual showed.  If anybody has access to other reloading manuals and see something different, let me know. I don't want to pull these loaded rounds apart, but I surely will.

Thanks Huhgd, you know it is pretty bad when we can't trust load data manuals. I can understand some bad data from the 'net but this is crazy. That is why I stopped after the chrono gave me higher fps than the max load was showing. I may be contacting some load manual people to see if they can steer me to the correct data.
