Sounds like a chamber issue, not concentric, try and rotate a fired case and see if it chambers the same as you rotate. My FTW was inspected and came back with a new barrel and bolt no issues now. And accurate, took me about 100 rounds to figure it out. This would have helped me. https://www.sinclairintl.com/guntech/bullet-concentricity-related-issues/detail.htm?lid=16572
