I agree with Kremer_Mike....use a good wide broadhead. If you want more speed and still have penitration then you might want to change arroe size. I shoot a Martin Magnum. Jag Aluminum Arrows and 70# draw 29" length and speed it 310 fps. I use 4" Feathers! Ultra fine toon your equipment will increase everything and tighten your paterns.....Practice, Practice, Practice makes for a good and Archer
