The .338-284 has about the same case capacity as the .338-06. The shorter, fatter case may have slightly different burn properties, but my best loads are as follow with group size at 100 yds and approximate velocity:
3/8" 180 gr. Accubond 53 gr. RL-15, 2,800 fps
5/8" 160 TTSX 57 gr. Varget, 2,900 fps
3/4" 200 Combined Tech. 53 gr. Varget, 2,700 fps
7/8" 185 TSX 54 gr. Varget, 2,800 fps
I didn't get a chance to chrono, used best estimate from available data. I tried a number of loads with a good selection of powders that were recommended for this caliber. The other loads weren't nearly as accurate as these.
Hope this helps.
