Interesting condition at the range this morning. Went to load one of my unfired, factory fresh 6mmBR Lapua cases and it would not chamber, bolt would not close. This was a 1 out of 100 situation.

Got home and checked the Ogive and was ok. Next checked the headspace DL and found it .010" longer than my barrels headspace. .012" longer than the factory fresh Lapua.

I only use an expanding mandrel to open up the neck on new Lapua brass before loading. It looks like I will have to begin checking the headspace on new brass as well before loading.
