[QUOTE="Chas1, post: 1421010, member: 15738"] Loaded up 10 rounds of 308 Winchester, Went to range, all fired w/o issue, no failure to feed, eject or stuck cases. headspace on 10 cases ranging from .002 above Wilson high step to -.0015 below high step. the average being .0005 above high step. I've been told the high step on the 308 Wilson case gauge is 1.634 if so then measurements range from a high of 1.636 to a low of 1.6325 with the average being 1.6345. And now for what might be the dumb questions but, I'll ask anyway. 1.) Does a .0035 spread on measurements make sense...is that sometimes normal ? 2.) My chamber headspace=1.632 so cases with longer headspace is this due to brass springing back Any answers and/or suggestions are appreciated. [/QUOTE]
