If your not willing to reload then get it rebarreled in a caliber you like. At the end of the day you’ll be cheap (500 plus change) into that rifle and have a better barrel than most factory guns. All you would really have in it is 500/600bucks. Douglas is 500 for barrreling/chambering and assembly.
ETA bolt face might a problem but there are plenty of good rounds that use a 223 bolt face 22-250, 222, etc
