For any tough game that has bone and or gristle for an arrow to fight through, especially if the hit isn’t perfect (and we sure don’t live or hunt in a perfect world), the basics are the same, above and beyond the trite and often imaginative “perfect arrow flight and shot placement”: heavy arrow with as much weight up front (foc) as you can manage (carbon is unsurpassable for this) and a sharp two-blade head. While I fully appreciate all the proven advantages to a single-bevel head, most of us still can’t get them as sharp as we can double-bevels (in no small part due to broadhead manufacturers lack of uniformity in bevel angle and thus, lack of good easy-to-use sharpeners), so I’m back to double-bevels for anything smaller than elk or European hogs.
