    I have been shooting expandables for about ten years .I have had great success with them , a great kill rate and recommend them to most that ask about them. When I started with expandables I started with spitfires 1.5 in cut and they worked great for years .But I wanted to get a head with a little more durability .So I switched to G5 tekan 1.5 in and had good success with it but they discontinued it.So two years ago when they were discontinued I went with the killizone 2 in cut . I figured since I was shooting 73 lbs and an arrow at about 500 grains 2in cut wasn't a horrible idea since so many people are having good luck with them. But I have noticed within the past two years only 25% of the deer I have taken have had full pass throughs resulting in a tough track jobs. I believe the broad heads are good and sharp and reliable.


    Have you guys that shoot 2in heads notice the decrease in full pass throughs since moving up in cut size?

    I feel that it would be just as difficult to push a 2" two blade through an animal as it would a 1.5" three blade, because of blade surface area. I used to shoot spitfires and had good luck, but i wanted a big hole on entrance too so i went with some Rage Hypodermics. Only thing i have shot so far is a coyote but the hole was great. I would imagine with your setup, just about any broadhead would pass through with a well placed shot

    Actually I think a 3 blade 1.5 inch has something near 3 inches of cut surface and a 2 inch 2 blade has around 2.5

    If u measure the cutting surfaces 1.5 inches of blade and 2 inches of blade are still 1.5 and 2.0. I'm still curious if anyone has noticed as I have the the decrease in full pass throughs with the increase in cutting size of the broadheads. I was thinking it might have something to with the increase of rib contact with the increase of width of the cut not the increase in cutting surface.

    I shoot 2" Swhackers and haven't had any issues with pass throughs...but they open up different than the Killzones too....so not really sure.

    I have shot 2" Killzones and they were great! This past season I decided to also try the Killzone MAXX's and those did great too! Every deer I shot I got a complete pass through. When deciding to go with the MAXX's I was worried about penetration issues with the 2 3/8" cutting diameter, but they proved me wrong. I was using Gold Tip XT Hunter Arrows at roughly 387 grains complete arrow weight. I now have changed my FOC with added point weights to 12.09% and will be shooting 125 gr Killzones next season putting me at the approx. arrow weight of 413.8 gr. I feel this is plenty for good KE and penetration.

    Shot placement being key on pass throughs IMO, maybe you hit some bone.

    I agree with hitting bone especially a shoulder it will decrease the chance at a full pass through , but it's been on a quite a few animals I have killed. A few times the arrow has penetrated to the opposite side of the entrance side and just bounced of the rib cage and upon cleaning the animal I find the hard red hemmorrhaging on that side of the cage. I'm just figuring with my setup ( Mathews monster 7.0 @ 73 lbs at 28.5 in and shoot a fmj at 490 grains with broadhead . I'd figure I blowing through the majority of whatever I shot with the overkill of a setup I have. I believe next season I'm going to go with something that has a smaller width/blade circumference so I can decrease the blade contact with the rib cage and maybe the arrow will have a better chance to make a full pass through, although I have good luck with killing deer I think a pass throughs will help with tracking jobs.

    It might have something to do with tuning or FOC.
