Loaded up some to run through my Model 40 MOS.

I have a LW barrel in my model 40.

180 Speer Gold Dot HP
9.2 grains of Power Pistol.
Federal Large Pistol Primer.
7 Shot string
Average 1333 FPS with std deviation of 6 FPS.
100 yards group from the bench was 6"

I have to redo this my screens were backwards and I may have some errors. That seemed low for a 6.25" barrel?

Seems a bit high actually for 9.2 of PP.

While I have seen some load this combination slightly higher, their guns were set up for those loadings. 
If you are working at the upper end of the extremes, I would suggest very careful hand weighing and verifying of your loads. 
It is the only way to be absolutely sure of your work.  Using any sort of powder drop is a guesstimate at best!

BTW, I wouldn't trust most digital scales, while there are some good ones, many do drift and need constant rezeroing!
When working with a balance beam scale be sure to clean or dust the "V" blocks and verify the via check weights that it is good to go!

I have varified and constantly check powder weights as I reload. This velocity is correct keep in mind this a LW threaded barrel with a tight chamber and 6.25" BBL.

Good point, I'm comparing it to a 4.25" barrel.

I like this post. There is much valid information here.

I feel that the Dillon powder drop is good to go when one measures ten consecutive charges. I wallop the handle really solidly for five and then work it mildly for five. I usually find a variance of a tenth of a grain either way. So if I set a max charge I go .1 under and enjoy life. I'm not loading national match ammunition and the variance doesn't affect me.

I wouldn't load with an electronic scale for magnum loads. If you are, record the weight of your measuring cup/sled. Mine gained 0.3 of a grain over the years before the scale died.  I made a note of this and used it to check the scale's honesty over time.  I agree that the digital scale is much faster for load development, but want of two batteries can bring things to a screeching halt. That's big money for batteries in the middle of a work up.

One thing that is telling me the charge weight is good a high count shot string and the Devation is very low.
