I drew a 110pound fiberglass backed and bellied bow - once. Guy at a shoot, said I could have it for $100.00 if I could draw it to my draw length. It was 100 pounds. I got it to my draw length of 29" = very close to 110pounds, then let down quickly, as that pulled 2 out of the 3 muscle groups off my right shoulder blade. My own bow at that time, was a Howard Hill 74 pound bow. We were at a 3-D longbow archery tournament (NA Longbow Safari) and I was done - had to carry my right hand in my pocket for the weekend. Awful time getting dressed and wiping my butt. LOL
I was a LONG time healing from that one. Should have warmed up first. LOL
My bro made and still has a 100pound Yew bow he made. Horn knocks, etc. Nice heavy bow and he practiced until he could draw it, to his chest. "Tod's Workshop", Tod Cutler, a U-tuber from England has an archer from the Mary Rose Society shooting a 160pound longbow in some of his videos, enacting feats of the 15th century.
The 1/2 dozen arrows Taylor made for the bow, have English made forged points, 6 different types. The arrows are 4/10" tapered shafts to the nock, made of ash, weighing 1,500gr. each.
Now, it just hangs on the wall with his other archery stuff, but he does shoot a long bow indoors a couple times a week.
He's good with a long bow, always has been - many BC and local 3-D championships on his belt. He's good, even at 75 yrs. old.
