B-50 will stretch like crazy for a while, then settle down. Shoot about 20 to 30 arrows and your brace height will drop at least an inch I would bet. I brace my wooden bows at 6 to 6.5. I suppose you know how to shorten or lengthen the string to achieve the brace height you want. But if you don't know, to shorten the string and raise the brace height, unstring the bow and let the top loop slide down the top limb, then slide the string off the bottom limb. If you slide the bottom loop off the bottom limb and twist it counter clockwise, your string will get shorter. If you twist it clockwise your string will get longer.
