we have been having some abnormally dry weather here recently. I pulled a bow out that I had done a repair on. A splinter lifted on the bamboo. The bow was 57#@ 28" I tillered out away from the splinter a bit and dropped the weight to 50#. This is a bbo, the bow weight went back up to 62# just because the osage dried out. I still can't believe it. I checked an old elm self bow I have been shooting for at least about 8 years now, weight went from 50# to 58#. great weather for breaking bows. Steve
