RE: Penetration test
The test was more for fun, read into it what you want. It is relative test only. I don't think I am going to buy some scapulas and then clean the mess up and replace a bunch of arrows and broadheads. This is a chain thread and its been passed on to you grndhntr! Your turn!
Ok seriously, as good as Zwickys are they are meant for a slower heavier arrow. I am betting that the two broadheads will break any bone in NA. I wouldn't stake my life on the Stiker but I would on the Stinger. The Striker is one awsome broadhead though. I am not exagerating about the sharpness and its the first broadhead I've seen stay sticky sharp after shooting into a foam target a few times. Weight is definately a factor in driving the broadheads deeper as the "test" shows.
"There is no way that any modern compound should fail to fully penetrate a WT deer." I agree. Most of those flag waving situation are probably caused by poor arrow flight. Poor tunining being the major cause. If you want to see penetration check out the elephant video on the Excaliber site. I don't have the specs on the equipment for that shoot but I bet Dan does.
