Gouges on the Head Stamp
Sounds all well and good, maybe shooting the 55 grain and working the action for a period will work. But I still say, and most reloading books show that that ejector mark on the case head, is one sign of too high pressure, for that given load. I would just feel safer and more at ease, with just not shooting that load of Nosler's and work up one that is slightly lower for your rifle/chamber. But that is just my opinion. Bill K

Another reason the 'ejector marks' show on new brass is if the case head to datum line is markedly shorter than what a piece of fired brass fired in the exact chamber measures.
Check the datum dimension on new brass and compare it to a piece of fired brass. Make sure to remove the primer from the fired case as it will change the measurements by a few thou. |

I'll check the sample, I have and report back on the results, if anyone else has a sample, if they will measure the datum to case base dimensions, and get the same info from loaded OEM ammo. We will have some more info to digest etc. Tia, Don

Guys
Using the Hornady tool, with the .330 insert, the datum line to case head measurement comes to, 1.450" for this fired case. What is the datum measurement you find? For live OEM ammo? HTH, Tia, Don
