Has anyone shooting a Rem Police in .223 notice that primers cratering up around fireing pin, I checked size of hole on bolt face mine measures .078 I checked my Rem 700 in 30.06 its .065 I am consered as I was loading Varget with 75gr HPBT Hornady,s I am still below max and they crater quite a bit never seen this before

Cartering is as much a sign of poor firing pin fit as it is pressure. I am not sure what the remedy would be other than refitting a new firing pin.

Don't feel too bad, Manitou. My new 700 SPS Varmint in .223 does the same thing. Craters primers with factory ammo, and anything approaching factory pressure levels. If I back down my handloads to .222 Rem levels, the primers look fine. I will probably just live with the cratered primers, since I am confident my loads are not generating excessive pressures.

how tight the chamber is and head spacing could cause it too

Hello,
Not all primers are born equal. Might try a different primer in your reloads and see if there is any improvement???? Just a suggestion.

I have an LVSF and an LTR. Both crater with even mild loads. I don't worry about it anymore. Both are 3/8" 5 shot group guns.
