I have changed alot of savage barrels and I dont remove the ejector, dont feel its needed. I also dont use a no-go any more, unless its a caliber I already have the gauge. I do use the scotch tape as a rule. I use a fired case resized by my die as a go gauge when possible. But my guns almost never shoot factory rounds, most never have. There will most likely be at least one loud protest to not using both, store bought, go and no-go gauges... But I promise your gun will shoot great and you wont go to hell. That being said, if you had trouble extracting the fired case, that would give me concern and I would check it out. The case neck stretching would be a major red flag. What caliber are you working with? Bill
