I've been trimming cases to 1.750. Trying to load for precision so Im trying to do everything right. I had 3 rounds of black hills 77gr on the desk and I measured the cases. They were all different, 1.753, 1.757, and 1.759. What gives?
Shouldnt cases be at 1.750, and shouldnt factory ammo of this type be a little closer in specs? |

How do you know it's not the chamber stretching the fired cases out a bit inconsistently? Maybe the 1.753 piece was annealed more precisely and had a bit more spring back than the 1.759 piece? Inquiring minds want to know. Anyhow, two pieces of printer paper isn't a whole heck of a lot. Their brass isn't hand sorted, like the Nosler stuff, I'll gander. Don't sweat the little things.
