Are these primers okay?

[PA4476]

These were my max loads on some test rounds. 357 mag, H110 17.0 gr, 158 gr Berry's Plated bullets, WSPM primers..... Do they look okay or too much pressure?

According to the Hodgdon reloading data I am looking at, you are OVER MAX load by .3 grains. So I would say they are too hot.
357 Mag
158 gr bullet
Hodgdon H-110 powder
min 15 gr ------ MAX 16.7

From Berrys web site:
Velocities depend on the caliber, but as a rule of thumb, we recommend you don't shoot our plated bullets over 1250 feet-per-second. Our 44's actually shoot best around 1150 fps. 45's are generally good at 850-900 fps. Our bullets are not recommended for magnum velocities over 1250fps unless the bullet description denotes a thick plated bullet with a higher listed maximum for velocity.

All different headstamps? If the load shoots well pick the brass with the least flattening/cratering. It's thinner brass yielding more case volume and lower pressure.
