I have a 38@28 Osage bow I am going to test against the mulberry. These bows are within 1/2” in length and almost identical width measurements. The Osage weighed 24.4 oz. the mulberry weighed 20.2 oz. I have a arrow that will be shot as close as possible to 28” through a chrono . The Same arrow will be shot from both bows and average the shots. I’m curious. Coming soon . The arrow weighs 384 gr. Spines for 40# bow.
