Data for 180g 10mm lead bullets?

I can't find much info on this bullet in my manuals. I see 170g lead and 200g lead, but no 180g.

I loaded up a dozen each of the following with W231 under Oregon Trail Laser-Cast 180g lead bullets:
5.1g
5.3g
5.5g
5.7g

The 5.7g was the most accurate of the bunch. It didn't show any pressure signs aside from flattened primers, which I expect with 10mm in the first place.

Anyone know if 5.7g is close to or over the max for this bullet? Thanks.
