Yes. You understand. I doubt there is a single person reading this that has only placed a live round in a chamber while at the range.
I bought a bolt action and it would not chamber a round. The store owner took a few live rounds from new boxes and the bolt would not close.
He tried to chamber them in the store. He sent it for finish reaming and it now shoots well.
People do this all the time.

I didn't mention before in this thread that I did have a slam fire while at the range.
It was while chambering a round and letting the bolt slam forward.
I have been worried about slam fires ever since. I didn't think they were possible before that.

Well since you put it that way, it makes perfect sense to me now.

I have reloaded every Grendel round I have fired. I test live rounds in the chamber when I load the first round of a batch. You can tell if the cartridge fits properly with the upper removed and simply sliding the round in the chamber and carefully sliding the bolt carrier into the upper by hand. The bolt should rotate easily. You do not want to be jamming improperly sized rounds into the chamber only to have to figure out how to remove the round.

You can also close the bolt on a live round in a much more controlled manner (gun assembled in a safe location) by using the forward assist (if the upper receiver is equipped with one) to close the bolt while holding back on the charging handle. This is how I chamber a round when I am hunting. To do it even more silently, you hold the charging handle back so that the forward pressure you are putting on the bolt carrier is held back by the backward pressure you are applying to the bolt carrier by the charging handle. After the round has started to strip off the magazine you used the controlled pressure of the forward assist to ease the bolt close on the round. This prevents the bolt from going closed with a clank as the extractor clips onto the chambered round.

FYI. You can use fired primers when loading dummy rounds.
