What do you like to use to support cables in a concrete ceiling with little other structure available? Mounting J hooks around the wall is an option but will be extra length to the runs.
I found these plastic rings by Caddy CR-50 that look promising.
I don't own a hilti and no plans to acquire one.

Get or rent a ramset masonry nail driver, save a ton of time no matter what hanger you use. You could use ceiling mount J hooks also if distance is critical.

Look into a cable tray. Fewer holes to drill or shoot than j hooks.

I agree with Jim, cable trays may add more cost but in the long run will be easier especially if alot of cables are involved and add ons are going to happen.

Also agree with Bill. Best roughly $100 I spent. If you do it get the trigger model not the one you whack with a hammer. The extra cost is worth it.

we did some work in an old building and the electricians were there and tried shooting into the ceiling and either had blowouts on the holes or no penetration. We ended up getting some 1/4 x 20 threaded drop in anchors and screwing hooks hooks to them.

I owned a top of the line Hilti (nailgun) back in the '70s. I didn't like it. My guys went to mount some 202 chambers on (what they thought was) a concrete block wall. Turned out to be cinder block. They blew the nail through the wall and out the other side. Lucky no one was hurt.
I prefer a hammer drill and double expansion bolts.

Recently I saw school maintenance using a Bosch RM540 rotary hammer to core 3 inch holes. Before I invest in one anyone else have any experience with it?
