I have read the previous threads about FL vs NS, and I have a question. I want to see if I got this right. If you have a factory action, with a factory barrel then you should lean toward NS because of the looser tolerences. But if you have a custom/blueprinted action, and a custom barrel then go with the FL becasue of the tighter tolerneces. This is just to make sure the case/bullet will chamber, and for better accuracy. I just want to add this as well. I know that every rifle, case, bullet, powder reacts different, my question is more or less speaking in general terms. I am not looking for a short cut, or asking someone to look into a crystal ball. I just wanted to make sure I have the "Theory" right.
