Brand new rifle, new Hornady ELD Match ammo. I only have 40 rounds and thought I'd buy factory first, then use that brass as a base. After cleaning, I measured everything. Then resized thinking I have a chamber sized case. I was a bit surprised that the case grew at the shoulder by .003". I haven't pulled the rifle out of the safe to see if it has an issue chambering the empty case (after work task). Is it normal for factory new brass to be so undersized it takes more than one firing to fire form? I'd hate to have to need to have the HS checked on a brand new gun.
