@Jordan Budd has been shooting Day Six Gear arrows and broadheads for a couple of years and has some great things to say about them. Check out her review below.
I've been using Day Six arrows and broadheads for about 2 years as well and have had nothing but good experiences on about a dozen animals. Both the arrows and broadheads are tough as nails. Here's a photo of my arrow from this year after it went through a bull elk and embedded in a tree. I cut out the broadhead from the tree and put it back in my quiver and it was still plenty sharp to kill another bull.
Over the last few years I’ve been fortunate to have a large amount of success with a setup almost identical to the one [mention]Jordan Budd [/mention] mentioned in her review. From antelope and elk at distance to mule deer and whitetail up close this setup has performed flawlessly
I like where their head was at with the high-end stainless. I much prefer stainless for long backcountry trips. Although, I kinda wish they went with CPM-3V for better toughness. (I chipped a few testing a different fletching pattern... but what i hit would be a tough ask for any broadhead). I switched back to some tougher A2 steel heads. Still bought some replacement blades for the Day Six heads. The Day Six sharpen up well and keep a nice edge!
