Zwickey Delta 4 blades....too many kills over the last 30 years and over 100 kills...
Went on a tear(before TX) here in GA with a 33 yard recovery rate on deer for over 25 years.
Had the same great results on hogs....
No ONE SHOT ONE KILL PICTORIAL from me...but 3 decades of kills....including one night of taking 2 bucks and one doe in 13 minutes...yes, it was legal.
Why? Cause they work...they are tuff....they are 4 blades and produce more blood on the ground ( I know some will argue but you wont convince me, I"ve been on too many blood trailings with all sorts of heads and I know what I saw, a slit will not bleed like a hole no matter how you spin it...see which leaks most, a slit or a hole in an oil can)...the bleeders are just enough to make them bleed more and cause more damage...but not enough to impede penetration. If they impede penetration, you hit the wrong spot and there is no guarantee any head will penetrate a bad spot. Remember, a man once shot a polar bear with one, and he didn't see the other bear behind it.....and his one shot killed BOTH....so don't go telling me they wont make two holes if you do your job.
They also cause more damage...making the animal sicker quicker and making them lay down sooner.
They HOLD AN EDGE....I've shot deer in a bean field and knocked the dirt off a pass through and could have shot them again.
Durable...I killed 14 deer with one head...and retired it after almost loosing it on a TX hog. Never had a quality issue with them. and never had one 'come apart' like some claim and again...been shooting them for over 3 decades.
Some folks talk about how good their broadheads fly... all broadheads will fly if your equipment is tuned and your broadhead is mounted properly and you have good form... and good form is Paramount... it doesn't matter what kind of Broadhead you have if your form is no good or your equipment is not tuned.
And I have killed some great animals with wide 2 blades...and 3 blades....it was hard for me to try them due to the track record I had for so long with the 4 blades....There are some great narrow 2 blades on the market as well for animals I don't chase...or needed with the bow weights I use.
As they say you got a dance with the one that brung ya... and she's still looking good.
Sorry...you asked...and that's my rant
