They're almost certainly saying bullet but meaning casing. But yes I have to say that it's pretty unlikely.

Not seeing other outlets report this. So yeah I'm skeptical.

I'm not saying this is the case, but it is very possible that if this person purchased the rifle legally, they believe that the purchase will be traceable back to them and that they will almost certainly be caught. So they could have acted with the mindset that they would be throwing away their own life.

I dunno why they wouldn't display both. Also cynical me thinks this is a more useful change for advertisers than users.

That said this would probably be useful for post ranking on the back end, if they're not already using it. There's always been a noticeable thing on reddit where posts on large subs with little activity don't seem to bubble up much on /r/popular. Which makes those subs seem even deader because they don't get new blood.
