Only one thing to do, and that's sell your rifle to me for $600 or so.
On a serious note, another vote for reloading here. Depending on caliber and how hot you load, you can get 3-4 shots per brass case. Primers and powder are tough to come by, but that's just the times we live in, and times change. Saving money, plus the ability to custom-load ammunition that YOUR rifle likes, will be satisfying both in the short term and the long term.
