Are 4 blade broadheads for real?

 Here is some good blood from a Zwickey Delta 4 blade.

2012 hunts all single blade all with two holes all with good blood.

Nayala 12 yards 50# TC Abowyer Bonehead RW single bevel.. Pass through...

Impala 18 yards 50# TC Abowyer Bonehead RW single bevel.. Entry last rib left side, arrow went through the vitals and came out the neck on the off side just behind the head with 12"s protruding on the exit.....

Red Duiker 17/18 yards 50# TC Abowyer Bonehead RW single bevel.. Quartering to me broadside pass through...

Blesbuck 15 yards 50# TC Abowyer Bonehead RW single bevel.. Broadside... pass through...

Missouri Whitetail buck 45# Mike Tenley recurve (tradgang bow swap gift) Silver Flame (German) double bevel....  slight quartering to me...  pass through to the fletch pull through when the buck ran....

I use paper wheels and polish my blades they are so sharp that animals start to bleed before they hit and I work very hard to get my arrows to fly right. I shoot light equipment because I have to but it serves me very well.

I'm sure 3 blade and four blade work equally well for others but given my physical limitations I have gained a great deal of confidence using wicked sharp quality single blade heads with well tuned arrows.

Magnus Stinger 4 blade put down 2 of the 3 deer I shot this year. Not huge blood trails, but 2 of the 3 died within 80 yards. The other deer left a good blood trail for a long way, but ultimately wasn't recovered.

I still have an arrow tipped with a 4 blade Delta on top of the Bighorn Mountains after it passed through my first P&Y bull elk. I never found that arrow, It kept going, and going.
