I just purchased a sportorized Arisaka that looks exactly like this one:

How do I verify the chambering of this rifle please?

Thanks,

Only way I know is to make a Cerrosafe chamber cast and measure it.

Or tie it to an old tire and shoot it with a long string to get a fired case.

If it blows up, it wasn't what you thought it was! :what:

Probably not the most accurate, but will get you in the ballpark.

Stuff some cotton down the bore after the lands. Then pour some wax to fill up the chamber. Push the wax out with a cleaning rod and jag.

That's the poor man's way. Does a pretty good job but not as good as a chamber cast using materials designed for this. I've done this to verify the throats of the chambers. The end result will vary a few thousands but should be good enough to tell what dimensions you have. I guess you could close the bolt as the wax dries.

Be warned, this could be messy but easy to clean up.
