Jacketed subsonic?

[360hunt]

I have done reduced loads or subsonic for small game while hunting moose and elk.
Just easier to carry one firearm.
I always used my cast bullets but have recently changed calibers and found myself with casts bullets.
I have a ton of jacketed...... has anyone here used jacket for subsonic here?
Any precautions? I would assume it's fine but thought I'd ask some freeloaders first.
Thanks 360hunt
