Muzzle wear gauge

[Beltfed]

Can one use an M1 Garand muzzle wear gauge on a carbine. I have picked up a very early non modified carbine. History….no idea other than it set in a sale for a long time. Thanks

A 30-06 is a 30 caliber round. A 30 carbine is a 30 caliber round. The muzzle gauge works. The throat gauges are different.

Same muzzle gage for carbine, garand , 1903 etc......................

I use machinist's gage pins for checking mw. I can measure how deep the belling is to clean it up.
