any well constructed hunting bullet will work fine. There's no magic involved. Pick what shoots well and personally, id keep it at or above 180gr for cup and core, and 165 gr and above for copper solids. However, I wouldn't worry at all about using a 165gr partition (or similar).

Because through judicious handloading and a bold sense of optimism, you can make anything into an .88 Magnum - once! 😁 - chesterpulley
