Not so much "big holes"...there could be a lot of blood. It all depends. Eskies fly great, they fly quiet, they sharpen easy, they are very dependable & durable and they look good! They penetrate as well as any excellent BH and yes, they will make things bleed when placed appropriately. Sorry no pics of my kills with Eskies but myself and bros have had many deer kills w/Zwickeys.
Jack Zwickey is the nicest man you could ever meet, a real gentleman. Hard to find something bad to say about any Zwickey head!
Best of luck!
