If it were me I would shoot something like these:http://www.lancasterarchery.com/solid-legend-175-dangerous-game-broadheads.html
380 has plenty of KE and the extra 25 grains will help penetration and won't slow you down that much.
The only potential hangup is whether they will group okay out of your 380.
The solid broad heads have a reputation for being super tough and razor sharp.
The zombie slayers are a very good bolt and much tougher than the factory excalibur diablo's but even they have limits and will shatter if you hit heavy bone. I broke both shoulders on a 260lb whitetail using a zombie shaft with a mechanical last winter. The bolt shattered on the offside shoulder blade but did destroy the shoulder as well. The deer dropped on the spot. I am sure that if I had been using a fixed blade the shaft likely would have remained intact as the one of the blades on the mechanical broke in half and the other was bent.
The only carbon bolt I have ever shot that seemed indestructible were GT Pro IVs (They are now called Nitro Pro). On a 20 inch shaft they are about 95 grains heavier than the zombies. I have actually had them hit rocks (after a pass thru) without shattering.
Good luck on the hunt and looking forward to the report.
