OK Thanks. 243WinXb Thanks for the photo and explanation! I ordered a L.E. Wilson head space gauge for the 338 Lapua. Since my RCBS die is in my opinion down sizing the neck too much and scarring it, and given the amount of force it
takes to pull the expander ball through even with lubing the inside of the neck, a friend of mine said that I may be pulling the case shoulder out of whack, so if
this is happening I hope the head space gauge may confirm this theory. I am ultimately trying to figure out why my Savage 110 BA wont group better that
1.25 MOA AT 100 YDS. I have tried a bunch of loading combinations using Retumbo (88 - 92 grains), H4831SC, and IMR 4350. I am using a 250 grain scenar bullet and off the rifling from .015 - 0.25 inches. Using Federal 215 primer. Nothing seems to work well and frustration level is high working with this
particular gun. I called Savage and they say test fire their guns for accuracy using Black Hills ammunition which I cannot find here anywhere.
