For those wondering about the latest market evolution in premium, monolithic, single bevel, and heavy (don't call me fat!) broad heads, the Bishop 315 is a fantastic tool. I use heavy 2 blades and mostly single bevels for pig hunting as I complete product reviews 12 months a year. (This is pig #31 in 2017). Pigs will push your arrow / broadhead setup. Or put differently, if you can kill mulitple pigs with your setup, whitetails are ice cream. My nephew Sam killed his first pig, quartering in, complete pass through, broke through shoulder, cut 2 ribs off spine and into the dirt. He thought he missed it was so quiet. I dare say it is incredibly efficient - we continue to have the same kind of results. No sound on impact, just a quiet "Chut" sound. Check it out and come back here to comment. I'd love to hear your thoughts. Thanks to Bishop and Lumenok for providing great products and helping Sam. -Ranch Fairy Out
