I like big VPA broadheads for big animals.
They are machined out of one solid chunk of steel.
The most accurate, long lasting, and toughest broadhead I have found, and I have tried a bunch over the last 40 years.
I shoot them on my arrows year round, they sharpen up nicely when the hunt comes. I like the 150 grain 3 blade but they are all awesome heads. I have shot pass through shots on deer and still kept the head in my quiver, and it still shot great at 90 yards.
