The only downside for me was the tip strength. As much as I wanted to love the 100gr Black Hornet Ser Razors 2 of the 3 heads in the package exhibited tip curling when shot the first time into a new 18-1 Rhino target. I did not bother to shoot the third head as I was already convinced. The distance was 25 yards using a 340fps TenPoint Eclipse.
Accuracy was not an issue as they flew great but just as I suspected, the chisel tip design turned out to be superior in strength to the cut on contact design, at least for me.
I know I could have returned them to Magnus with there generous return/replacement policy but probably won't. Instead I will go back to using my tried and true 100gr SlickTrick Magnums that I have used for the last 20 years with both verticals and horizontals. They have never let me down as long as I have done my part correctly.
I have no qualms with Magnus whatsoever, they are a fine company with a great reputation.
I wish all those who use them well, unfortunately they weren't the best head available for me.
