Here are my reloads, .357Magnum brass :

I'd say those are "mildly" crimped. The crimp is noticeable but does not bite the bullet.
I only loaded 20 rounds of each variant for my testing session and shot all of it. I usually measure bullet speed only with validated recipes to evaluate consistency within a batch and from one to the other. So no chrono data available yet.
I'll make a new batch with 158gr HT-LSWC and Bullseye, and change to Federal primers with a heavier crimp.
I only shot factory ammo with this gun just before I bought it. Shooting one-handed bullseye-style and not familiar with the sights, I got shot a 5" group, 5" from POA at 7 o'clock. I don't think it means anything.
I'll be back.
