I've not tried these but Barnes has two 375 round nose flat point 255gr bullets that might work, the 30496 designed for 375 Win and 30497 for 38-55. They may be a bit lightly constructed compared to the original but for deer and such may be OK. I currently load a Lyman cast GC 264 gr #375449, the old Hornady FP 220 until my supply runs out, and the Speer 235 SP.
