I've also gotten Wes's processed .223 brass. 99% have been between 1.740-1.750. Any under 1.740 I trash. I also have a lot of factory .223 that I bought new. They all all over the place. Some 1.758 and even as short as 1.735. All of that factory ammo shot fine. No issues.
For just plinking and punching holes in paper I guess close to spec is good enough.
