Have a Remington long range that had extraction problems. Rebarreled and chambered for 28 Nosler. Third firings on brass would have to strike bolt to get it to slide open. Pressure good, (lift easily just wouldn't break case free). Took it to my gunsmith, found out bolt was out of time and lost most of cam action. Reattached bolt handle within proper spec works great. Just wondered how many others have experienced this.
