1903A3 throat and muzzle measurements

[lrgrendel]

Recently bought a 03A3.
Any tricks on how to measure the throat and muzzle with out buying those expensive tools?

Again just looking for information on measuring my rifle.

Thanks

Take a loaded round and put the bullet in the muzzle. Does it eat the bullet to the casing? How does the crown look?

As far as throat erosion, you may want to get a bore scope. There's one for $50, I think it's called a Teslong. Itll connect to an Android phone and has pretty high resolution.
