Anyone use 700x for 10mm?

Lyman's 50th edition is the only thing I have that offers load data with 700x in 10mm. I wanted to try some Berry's 200gr bullets and Lyman lists 5.8gr as the max charge, so I went with 5.0gr.

I've had the 10mm almost a year now and this is the first time loading for it. I'm pretty hesitant because I don't like not being able to hear the powder in the case when I shake it, but I did measure and it looks like I have a minimum of .035" of airspace between the powder and base of the bullet.

Should I proceed? I only loaded 15 rds.

The load shot fine, very mild actually. Even with a few more tenths of 700x, it still wouldn't be fast enough so I think the next load I do with those Berry's bullets will be with Power Pistol and Blue Dot and if this shortage of everything ever ends some 800x.

Oh, and the other good news I can report is no Glock smiles on the brass after I shot them in my Gen 4, so my concerns about that being an issue are now resolved.
