Learned something new today

[Chief-7700]

Was having some problems with my 9mm 125 grain T/C flat point loads fitting my case gauge. Called Jimmy Mitchell (www.bulletworks.com) who cast all my bullets for me, Mitch told me that "case gauges are built for jacketed bullets not cast"

How does the case gauge know? If it doesnt fit in the case gauge why would it fit in the chamber?

I quess my case gauges have been lying to me! Use them on all my FMJs & lead pistol bullets.

Waitasec...I could be mistaken, but aren't case gauges supposed to be used on empty cases, i. e. no bullet in there? The only way I can think of the bullet making a difference is an OAL measurement.

from my understanding.. case gauges are used with the bullet. to see if your crimp is right and also to determine if your OAL is withing standard.. if none of these are correct.. or within the limits.. then your bullet will not fit the case gauge. please correct me if i am wrong.

Case gauges are supposed to be made to minumum standards.
Lead bullets are commonly 0.001" larger than jacketed bullets.
Therefore, a properly made case gauge should NOT accept an oversized bullet, even though the actual chamber in your gun will take them just fine because chamber throats are made to be BIGGER than the maximum spec on ammo.

Unless you are loading for an unknown gun, you don't really need a case gauge. Take the barrel out of your 9mm pistol and do the plunk test. Yes a case gauge is more convenient than your barrel, especially when it comes to revolver rounds or with a fixed barrel pistol. I don't know if your barrel will come out, but for most autoloader pistols, what better test is there that your round will or will not fit than the barrel you will be actually using.
