This is a test of the 125 gr SEVR 2.0 Hybrid.
Here is summary of my 2025 Testing Procedure & Scoring w/the scores of this head posted in parenthesis as well.
1. Flight Forgiveness (20%, 23 pts)
I’m using a Killer Instinct LogiX435 crossbow, mounted to a BOG tripod, shooting a 685 gr Bishop GOAT bolt (310 fps) @ 30 yds. Field pts consistently hit in the 10 ring & bullseye. I use the exact same bolt to shoot the broadhead. The only diff in the 2 shots is the broadhead’s flight forgiveness vs that of the field pt. A bullseye gets a score of 11/10, or a score of 22. The 10 ring gets a 10/10, or 20 points; a 9 ring gets a 9/10 or 18 points…& so forth, w/ each wider ring being 1/2″ farther from the bullseye. Mechs are also given 1 Bonus Point for extra forgiveness.
2. Cut Size (20%, 21.12 pts)
The more tissue being cut, the more lethal the head, all else equal. The entrance cut, total cut, & width of the cut (a crucial variable for bloodletting) are all scored:
The entrance cut size is compared to a standard of 2.5″ then that fraction is weighted to 7% of the score. (2″+.7″=2.7″ =7+Bonus = 7.56 pts)
The max cut size is compared to a standard of 2.5″ as well, then that fraction is is weighted to 7% of the score. (2.7”=7.56 pts)
The max cutting diameter is compared to a standard of 2.0″, then that fraction is weighted to 6% of the score. (2″ = 6 pts)
3. Blades (20%, 19.19 pts)
Initial sharpness 9%, 172 grams = 10/10 =9 pts+.28 Bonus=9.28 pts & Edge Retention (9%, +5 grams = 9.90/10 = 8.91 pts) are measured using the Edge On Up Sharpness Tester. The pressure needed for a blade to cut thru a copolymer wire is measured in grams.
Edge Retention is the loss of sharpness after the head is shot in Pen Test 1, thru 1/2″ MDF & 2/3″ rubber foam mat & Clear Ballistics FBI gel. For every 50 “grams” of sharpness lost, 1 point is deducted from 10.
What are some sharpness scores for common edges?
A butter knife takes 2000 grams of pressure to break the co polymer wire.
A new high end cutlery edge: ~ 375 grams of pressure.
A utility razor blade: 200 grams.
Based on the many broadheads I have tested, here is my scoring scale:
Out of the Box Sharpness:
0-200 gr: 10
201-300 gr 9
301-400 gr: 8
401-500 gr: 7
501-600 gr: 6
601-700 gr: 5
Ease to resharpen or replace blades is judged & given 2% of the score. (5/10= 1 pt)
4. Penetration (20%, 15.46 pts)
There are 2 penetration tests:
Pen Test 1: 1/2″ MDF, 2/3″ rubber foam mat, Clear Ballistics FBI gel. Depth of penetration is compared to a standard of 9″ & weighted to 10% of the score. (8″ = 8.89 pts)
Pen Test 2: Layered cardboard. # of layers penetrated is compared to a standard of 70 layers & weighted to 10% of the score. 46 layers= 6.57/10=6.57 pts
5. Durability (20%, 19.63 pts)
Each head is shot thru 1/2″ MDF 3 times. Its condition is judged 1-10 & weighted to 12% of the score. (10/10=12 pts)
If a head survives that, it is then shot thru 22 ga steel plate twice. Its condition is judged 1-10 & weighted to 5% of the score. (9.25/10=4.63 pts)
It is then shot into concrete once. Its condition is judged 1-10 & weighted to 3% of the score. (10/10=3 pts).
Steel plate & concrete are certainly not “realistic” mediums, but they do reveal the outer limits of a head’s durability.
Bonus:
+1 Blades lock open
+.5 Blades can lock closed for practice
+2 Sharpness & Edge under 200 grams
TOTAL SCORE: 101.90 pts =10 Golden Arrows
