HELIX FJ4 150 gr Broadhead Test

This is a test of the 150 gr Helix FJ4 Single Bevel 4 Blade broadhead by America's Best Bowstrings. Here is summary of my 2023 Testing Procedure & Scoring w/the scores of this head posted in parenthesis as well. FJ4 150 gr Total Score: 81.45 = 8 Golden Arrows 1. Flight Forgiveness (20%, 15 pts) This is not just a test of how heads fly out of my bow, as it was in the past. With a well tuned bow, properly built arrows & good form, almost every head flies well. That's why in the past most heads got a flight score of 9 or 10. But that doesn't help those who may not have perfectly tuned bows/arrows/good form. So now I am gauging Flight Forgiveness. This is based on how the head flies for me, how well it spins, how "sensitive" the flight is to imperfections, & the exposed surface area of the blades. The max score of a Mech is 20 & the max score of a Fixed is 16. 2. Cut Size (20%, 16.62 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. (1.32”+.94” = 2.26” = 6.33 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. (2.26” = 6.33 pts) The max cutting diameter is compared to a standard of 2.0", then that fraction is weighted to 6% of the score. (1.32" = 3.96 pts) 3. Blades (20%, 16.9 pts) Initial sharpness (9%, 350 grams = 8.5/10 = 7.65 pts) & Edge Retention (9%, +75 grams = 8.5/10 = 7.65 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 Penetration Test 1, thru 1/2" MDF and 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. (8/10=1.6 pts) 4. Penetration (20%, 12.78 pts) There are 3 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 9% of the score. (5.25" = 5.25 pts) Pen Test 2: Layered cardboard. # of layers penetrated is compared to a standard of 70 layers & weighted to 9% of the score. ( 43 layers=5.53 pts) Angled Penetration Test: How effectively does the head penetrate 1/4" MDF covered by carpet at a 45 degree angle. This accounts for 2% of the score. (10/10 = 2 pts) 5. Durability (20%, 19.15 pts) Each head is shot thru 1/2" MDF 3 times. Its condition is judged 1-10 & weighted to 12% of the score. (9.5/10 = 11.4 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. (9.5/10 = 4.75 pts) If a head survives that, 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: -.25 pts bleeder bent back in cardboard layers +.75 pts thick blades (.070") +.50 pts single bevel rotation: 45 degrees at 10" TOTAL SCORE: 81.45 pts = 8 Golden Arrows Price: $25/head Special Notes: Please check out my sponsor, Stay Sharp Guide. https://staysharpguide.com or @Innovative Outdoorsman They make excellent broadhead sharpeners.
