I read decades ago that lightweight bullets at high velocities are hard on revolver forcing cones, especially thin ones like J-frames and even K-frames, which weren’t designed for continuous use with magnum loads. Eventually, heavier mid-sized guns like L-frames and the Rugers came out that could take the pounding, but forcing cones still will erode more quickly, even if they don’t crack like before.
If you’re stuck with those bullets because of the current crunch, I suggest you load them down a bit, maybe to where reliable expansion begins. Even at that, if that 360 is a fixed-sight gun, POI may be off somewhat.
Given a choice, I wouldn’t go below 125gr, and pretty much all I buy are 158s, jacketed or lead.
Years ago, my son used to go to industry seminars where those in attendance got to try out different products. The 360 was the gun that no one wanted to shoot twice.
