My steel plates get carried to an from the range in a case about 20% bigger than a brief case. So if plates , rope, nails, hammer can fit in that case , OK to go.

My method for hanging the plates for pistol and rifle ; a rope between wood or steel posts (like the old newspaper boxes used), always in front of dirt berm..
All plates have a hole near top edge with bolt thru hole from front and large washer and nut on back side. Hang the plate with bolt resting on rope between back of plate and washer. With this method plate hangs angled ( bottom edge furthest from shooter ) deflecting bullet splatter downward.

You can hear the hits because the rope doesn't deaden the sound. I paint the plates white to see the impact for the first dozen or so shots, helps to check your sights, scope zero.

Happy shoot'n
