I have a similar issue with bullets for my 375 Win, in particular the '375 Hornady 220 grain bullets'. I did find some Hornady bullets 220 grain at a gun show though. I also have Sierra 200 grain and Barnes 255 grain FN SP.
Also, I have molds that will work and I suspect that will be the bullets of choice for the bulk of my shooting. I'll try the Sierras and the Barnes - Barnes are sort of spendy, but if they shoot well...
Hornady's elimination of bullets is disturbing to me as I shoot a lot of Hornady bullets which are 'going going gone". I'm replacing them with bullets from other manufacturers. (Don't get me started on bean counters as I worked for "Sperry Computers" - shut down by stupid choices bean counters made and I worked for Westinghouse - also shut down by stupid mistakes by bean counters.)
I just hope the bean counters get out of the control seat of Hornady!
Wish you luck in finding bullets for your 33.
