There was a guy selling a "reamer" of some kind that would take a .223 caliber spec up to 5.56mm spec.
The pressures can exceed the max spec in a .223 weapon using 5.56 ammo.
People think they are interchangeable but technically not.
5.56 specs a tad bit larger. Maybe head space tolerances come into play as well.
If you have a .223 rifle at the low end of tolerance, the 5.56 ammo will fit, fire, cycle but the pressures can be high.
Even though it's only a few ten thousandths, damage (and or injury) can result.
It is a small diameter after all.
So this guy (in Michigan I believe) was selling this clean-out tool for way too much money.
A little grinder in the shape and size of a NATO 5.56 round.
Anybody heard of this tool out there?

Please seat yourself.
I like the very things you hate.
