Thanks for all the kind replies.
The string weight for those shots is 192 grains. Single loop flemish twist with a bowyers knot. 8 strands of d70 (fastflight/dyneema).
I could make an endless string and get another couple of fps out of it.....
I really will have to make that 510 grain arrow and she what she does with it. I think it's going to be high.
I might also dig out my bundle of flight arrows and go down the club....the field is 400yds long.....and it's a nice windless day here....
By the way Nathan i'm working on this bows sister at the moment...out of osage....lets see what the 'King' does with the same design! But no
I don't have an osage stash
