Quick question. Where do you find caliber stamps for marking the caliber on a barrel? Googled it to death and no joy.

It's called number and letter stamps.

Yep! One hammer wack at a time

Or, you can have them custom-made for each different chambering. Brownell's offers this service.

You might have them engraved on at a Trophy shop.

Or have it "Scripted" using either a Graver. I think I recall that Pacnor would script barrels.

Here is a terrible photo but you get the idea.

When I worked at APEX Rifle Company (more years ago than I care to admit). They had stamps for all the common calibers. I was looking through Brownells. But I couldn't find anything other than the letter and number stamp sets and the bolt on guide. I figured somebody had to still make them.

I have had three or four made by a fellow named Ray Phillips make them for me. He has a company named "Ngraver". Check with him.

Incidentally, since I got my "New Hermes" I find the 308, 22-250 and 223 caliber stamps I have are no longer used and would let them go. Email me if you are interested.
