Hello, new here and I have some questions. I have not shot a non-wheeled bow for close to 30 years. I have gotten the bug, and now own a Jerry hill long bow. It is 68" long and 50@28. I have been shooting some old 2117 arrows 29.5" with 125gr feild points. My arrows seem to be slightly tip feft nock tipping to the right when hitting my target at 20 yards. I have also shot 2018 arrows 29" with the same tips with the same results tip left nock right. All of my carbon arrows are plastic fletch so I have not shot them at all. Penitration is very simulas to my 50lbs wheel bow when shooting th 2117 arrow. accuracy is good when I do my part. Do I need to try more arrow sizes to get perfect straight line penitration? Perhaps 40% of the time with the 2117's arrows seem to be entering and going straight. Could it be my form or lack there of? Any and all suggestions are welcomed. Thanks, and this fun making it challanging again.
