If it didn't hit bone, it's possible that your bow and/or form could use a little tweaking to get perfect arrow flight. When you practice if your arrows seem to stick into the target with the nock end low, that's an indication. The arrows will still group together with corkscrewing, porpoising or fishtailing flight, but fixed blade broadheads and field points won't group together, and broadhead flight can get very erratic at any deviation in shooting form, especially at longer distance.
Putting a fixed blade broadhead on the arrow makes any imperfection in flight worse because the blades catch the wind. That's why lots of folks will use mechanical heads. But even with mechanical heads, if the arrow flight is bad, a lot of energy and penetration is lost if the arrow doesn't stick in straight.
I drive myself crazy sometimes shooting through paper and shooting bareshaft arrows, adjusting the rest and twisting cables trying to get perfect arrow flight. But when you get it, the arrow flies like a laser even with fixed blade heads and goes through the target straight.
Nice shot.
