Here some numbers using some lighter than stock (150g) broad heads.
85g / 350g total - 323fps (package of Stingers lists these as 85g, they acually weigh exactly 95g, you cant believe what you read apparently. The total weight is just a c hair under 350g)
125g/375g total - 313fps. ( 125g Montec weigh, 125g )
323 would be max speed as thats the lightest mass the 315 can shoot. cheers.
