[QUOTE="Bart B, post: 686903, member: 5302"] New brass fired the first time will have its case head pretty much take the same angle as the bolt face has. No resizing method will make it square again with the case long axis. Chambering that case after any sizing process probably won't get it indexed the same as when it was first fired. Accuracy will suffer; the better the high points on the case head and bolt face align, the worse it gets. If you want a tack driver, have the bolt face squared up with the chamber axis. Usually, the headspace won't increase more than 2 or 3 thousandths. If that's too much, go ahead and square it up then have the barrel set back and rechambered. Otherwise it may not shoot as accurate as one would like. [/QUOTE]
