Magnus 100 grain two blade screw in head:

Plywood: 5 points
Steel drum: 4 points
Tire: 3 points
Cutting diameter: 4 points
Accuracy: 4 points
Non-mechanical head 2 points
Blades: 2 points

 Total score: 24, with a blade sharpness rating of C

This head is very much like the 125-grain screw in head. The only real difference is the two vents in the blades. Most likely to get the head weight down to 100 grains. Accuracy is very good, maybe a hair better than the 125 grain version. In the steel drum the head got through the first side, with ½ the tip sticking through the back. In the plywood it penetrated all the way through with an inch of shaft sticking through.  The tire test was a bit strange. The first shot into it I broke part of a blade. It was just a small crack but it was enough to separate the two ends of the blade. This was with a new head, so I used another head for the plywood and steel drum test. No problems at all.  I then re-shot the same head that just went through the plywood and steel drum into the tire again. This time the blades stayed intact, but did squeeze down a bit. This is the first head that the tire did the damage, and not the steel drum or plywood.  Tires are very tough on heads, but it usually just chews up the blades. I am not sure why this head did not do as well in the tire as most others. It did however penetrate very well getting through one side with 12 inches of shaft. All and all this is a good head, accuracy is good, and it still is very durable. You will have to sharpen them to be “hunt ready”, but they are fairly easy to sharpen, and as with all Magnus heads you get their lifetime guarantee. If you want a wide, 100 grain two blade cut to the tip style head, this is a good one.

Please note as more test information becomes available, it will be updated and posted.  Make sure you check back periodically to see if the head you're curious about shows up on the measuring tape.  If you’re interested in donating a head for testing, email ckfitch3@aol.com or visit Huntingforums.com, Bows and Arrows forum and see 5shot.  Thank you and enjoy.  Return to the Main BroadHead Test Page.
