I have a very large friend I got back into archery. He drug his old Hoyte bow out and brought stuff over to shoot in my back yard. EVERY shot he took knocked over my target. Got the scale out and his full length aluminum arrows were 635 grains. Made a run down to Rainier Archery (long time ago) and his bow measured an 87 pound pull.
He would pull it back and hold it like it was nothing. I couldn’t pull it back!
Those are African dangerous game archery specs!
