I am taking mine to SA next month and have been working up some loads. I've loaded the 250gr. Speer into homemade cases from .375 H&H in front of 74 grains of H-4831 for 2550 fps and am getting 1 in. groups at 100 yds. I am going to stick with this for my load right now as it is giving me what I need. Also loaded 73 grains of IMR-7828 that gave me 2470 fps and good accuracy. BTW, I loaded the H-4831 load into 40 Stewart cases for the hunt. Both of these loads are a little hotter than the Woodleigh data but everything looks ok. I have a copy of the Woodleigh data page but it is hard to read and would not upload well. When I have more time I might work up something with the 250gr. Nosler....maybe the 225 load would be worth playing with as well. I would be really interested in some loads that approach the 358 Norma but would like to hear from someone who has done it.
