Inside of my 45-70 brass from Starline, I noticed some pieces have a distinct brass ring around the flash hole and some don’t. Does it matter? Today I shot one 5 shot group that measured 1 1/4” at 100, using a Lee 500 GC and 60 gr of OE 1.5. Next group had three almost touching and two that wandered away. Guess what, I have two pieces of brass without the ring around the flash hole. I’ll certainly get around to testing it. Has anyone else noticed the brass and if so, do you segregate it?
