Is 10 strands of B50 enough for a fiberglass backed longbow pulling 51lbs @ 27"?
It's strong enough, but my experience with B50 strings is they are kind of stretchy. You would probably be happier with 12 or 14. They seem to shoot better for me anyway.
Yes its enough I have a 10 strand on a 50lb recurve its perfect .030 serving
I shoot 12st on my 60# Silvertip, so I would think 10 for your 50# should be fine. Just keep an eye on it, and don't be afraid to change it when it shows signs of wear.....
I shoot 12 on my ~60# @30" bows... thinking of switching over to 10 strands though :)
What Guru said.
I have always used 12 strands of B50 for bows over 50# for long term durability and a thickness to ensure a tight nock bite.
I did some chronograph with my bow with both 10 and 12 strand strings to be sure of speed. I did not find a significant difference and was surprised to to see about 10 fps varince both ways (10 shots with each string - different arrows) The arrows were aluminum which I assumed to be the same weight. I used a thre finger under release.
Have you guys seen a perceptible advantage to a 10 strand vs. 12 strand?
OBTW, I use 4 extras strands in the loops to insure longevity.
If your bow is shooting well I wouldn't change it too much. Eeking every enth' degree of performance isn't alway a winner. For every action, there is an equal and opposite reaction. That's a law of physics. Make sure what you are doing doesn't have an equal negative effect that cancels out the benefit.
I'd be a little leery of 10 strandB-50 at that draw weight. I'd go with at least 12 strand. I've seen a number of "accidents" working for years in our pro shop. Forget the damn speed!! (nut)
I shot 10 strand b-50 out of 55 and 60# Martin bows for years, it does strecth quite a bit at first but once shot in was fine. Shawn
Im not doing it for speed just want to try something new is all.
