For those who've used both which one penetrates better? I haven't used the Killzone but did use the Double cross on a buck this year. In practice they are super accurate and open up nicely on a target. I got a great bloodtrail from the double cross on a marginal shot. It produced great entrance and exit hole. I clipped rear of left lung, diaphragm, liver, and punched hole right through stomach. It did go through the opposite side but got hung up maybe at the fletching. I didn't however get a "complete" pass through...I am used to broadheads just blowing through deer with my set up when hit in the ribs and pulling them from the dirt. I shoot a Xpedition Xcentric 7 66# DW, 29" DL shoots my 460gr Victory RIP at 287fps chrono and MBG sight tape verified. Wondering what others experience is so far with the double cross and if there are any penetration issues. Does the blade deployment system hinder penetration? Killzone better in this regard?
