Hi all, just got a Sempert-Kreighoff Drilling, 16x16x7x57R. I know that the 7x57R is a rimmed version of the 7x57 Spanish.

My question is, I've been informed that the gun may have been regulated for this round with 173gr bullet. Is there anyway or any info that would confirm this (BTW, the source knows his stuff, so I'm not doubting his word)? I know it has to be shot. Just looking for that warm and fuzy.

Thanks as always!!

Greg
