Muzzle damage

[BlasterBob]

Anyone see a muzzle looking like this. This is an M1 Garand. I'll have to fire it a few rounds to see if the accuracy has been destroyed.

This is on a WWII Springfield M1 Garand.

I have, it turned out to be lead buildup, gun was a Mini14...

Probably issued to a Marine. Rare and valuable (because it survived)!

Serious post... Doesn't look to be the actual crown but if you find issues or it bothers you, just re-barrel.

Not an issue, based on the picture.

Sorry, I have no idea how to post pictures other than via Photobucket.

That doesn't look like the threads are damaged from the picture. Have to use a muzzle gauge to see the wear but it looks fine for the rifle and age. Shoot it and find out.

The face of the muzzle is relatively unimportant.
The crown (the point where the bore exits the barrel) is critical, it must be clean and even.
The next critical area as mentioned is the bore proper, an erosion gage is a good thing but lacking that take a loaded cartridge and place the projectile nose down into the bore.
It should stop well short of the case, if it doesn't you have marked bore erosion.

OK, tried the projectile in the muzzle trick and confirmed it with an actual muzzle gauge. Gauge reads just barely a hair over 2.
Rubber band helped keep the ctg plumb.
