I’ve seen many positive things about shimming crossbow risers to fix downward string pressure but I need help with understanding what it actually does. I don’t get how making the riser 1/8” pushed out from the rail just make the string 1/8 inch longer when you pull back. I don’t understand how an added horizontal measurement would make the cams go higher up to release pressure on the rail. Can someone help and explain please? Or can someone send me some videos of doing it and explaining it I can’t seem to find any videos on it. Also I know shimming would probably work but does anyone know if there’s a more simply way such as just adjusting the height of the cams without adding shims. Please help so I can get this thing fixed and go out and hunt more efficiently.
