The 300 grain Uni Cor is my favorite bullet in the 444 marlin but I haven't seen a box for sale in a few years. I have a couple hundred left and a hundred or so loaded rounds and they will be used sparingly unless I see some for sale at a price that is remotely affordable.
That's what I use for bear spray in my .44 mags, good bullet. I hope to find some more in stock at some point, down to about 50 rounds.
