How deep should I seat this bullet? https://www.google.com/search?q=Hornady+.358+swchp&client=ms-android-verizon&prmd=smvin&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjjgZvov7HTAhWn6YMKHRJ1DYAQ_AUICigE&biw=360&bih=560#imgrc=pmDjmQF7No9zDM:
I'm loading it in .357 cases.

Seat it so it looks appropriate and functions. I go for about the width of a penny or 1/16th an inch exposed. They are soft swaged bullets so you shouldn't be pushing them hard enough that seating depth would casue any pressure concerns.
You can either seat so that there is approx. 1/16"-1/8" of the shoulder out of the case mouth and crimp into the soft swaged bullet. Or you can seat so the shoulder is a few thousandths below the case mouth and roll crimp over the shoulder.

Looks like a soft swaged boolit. Look for another similar weight and nose length SWC. Maybe the 358156 (Lyman lists oal at 1.590") if that's based on a 158 gr boolit.

Thanks, gentlemen. I was kinda thinking myself that about the width of a penny was looking good.

Yes, I know, and it's crammed waaay down in there at that length. I don't like the looks of it.

I'd go to the shoulder and probably not even bother to crimp.
maybe run them into my taper crimp die to iron the sides flat.

Yessir!
Seat them out as far as you can without having them protrude from the cylinder face. That maximizes boiler-room space, and allows optimum propellant for max velocity. But - it is a soft lead bullet, so I guess you aren't after max velocity. So - seat 'em wherever suits...
