I guess that’s what 50 years of improper drawing does:set1_rolf2:.Say what you want, but unless another injury it's sounds every bit of improper drawing technique and possibly over bowed. I'm 70 old and shoot all day if I want. My bows are set to 51, 53 and 55 pounds. If I want I can set one back to original 62 pounds and shoot quite a bit. I might get tired, but I don't hurt. Figure in 2015 a accident separated my shoulder, tore my rotor cuff in 2 places, shredded one area and had 2 partial tears.
