 Arrow Requirements 
 
 
 
 
 Spec 
 Value 
 Why 
 
 
 
 
 Spine 
 400 (stiff end) or 340 
 At ~65lb effective, 400 is borderline — 340 is the safer spine choice depending on brand chart 
 
 
 Arrow length 
 33" minimum 
 At 32¾" AMO draw, a 32" arrow does not clear the riser safely at full draw — 33" gives minimum safe clearance 
 
 
 Material 
 Carbon 
 Carbon Express Predator line specifically recommended by real Black Ridge owner 
 
 
 Point weight 
 100–125gr 
 Heavier point suits longbow efficiency — real owner confirmed 125gr 
 
 
 Total arrow weight 
 520–650 grains 
 8–10 GPP × ~65lb effective draw weight 
 
 
 Minimum arrow weight 
 520 grains floor 
 Never go below 8 GPP on this bow 
 
 
 Straightness 
 .006 or better 
 Standard for carbon at this weight class 
 
 
 
 
 
 Do NOT Buy These 
 
 
 
 
 What 
 Why 
 
 
 
 
 500 spine 
 Too weak/flexible for ~65lb effective — poor flight, inconsistent 
 
 
 32" arrows or shorter 
 Too short — point pulls back behind rest at full draw (safety risk at 32¾" draw) 
 
 
 Arrows rated "20–50lb" 
 Your ~65lb effective draw is outside their stated safe range 
 
 
 Fiberglass arrows 
 Not rated for this draw weight — risk of shattering
