I shot my “ new to me” 6 br barrel for the first time the other day. This is a Savage target action in a SSS bench rest stock, barrel is a 30” 8 twist.
I started loads down at 28 gr when using 8208 xbr, and N133, and varget. On a few of each of those loads i saw some very light ejecter marks on a few case heads, but not on all cases. I shot the loads of each powder with increasing powder charges watching very closely for pressure signs. I saw the same thing all the way to 30 grains. Only 1 or 2 cases of each 3 shot loads had this.
Primers were cci 450’s and were not all that flat. I have seen much flatter with my .223 with some win factory loads in the past.
My question, is it normal to see pressure signs at lower powder charges with new brass ?
