![[Linked Image from i.imgur.com]](https://i.imgur.com/fDZv7gQ.jpg) These is all the markings on it. Seems like a 6 groove. It is stainless.

I have no clue but I think you need to work on your hammer technique.

Toodogs is probably right. I've got several x-caliber barrel blanks and their marking method is different from the pic.. That's the thing, each manufacture has a slightly different marking system. Some use actual caliber designation ie. 6.5mm vs .264, or 270 vs .277 etc. Where the number "6" is on your barrel Jim, others put the twist rate. Can't imagine a 1:6 twist on a .243 barrel. Easy to check though.

No idea of the brand, but the 6 is for 6MM, and the actual groove diameter will be 0.2427". You could confirm that by driving a soft lead slug the length of the bore and measuring with a micrometer.
Ignorance can be fixed. Stupid is forever!

heres an XCal from out in the shop ![[Linked Image from i.imgur.com]](https://i.imgur.com/IgOLoeR.jpg) 0.2427" groove diameter. Six lands/grooves. This+10 . Mb I see it as .242 (tight 6mm) 7twist, 6 lands/grooves Oh, I didn't know what that meant. Just a guess cuz your both in Montana. The tight bore might be a better clue.

Check out the pic on this page. The layout of the numbers is the same, looks like Hart barrels. https://rifleshooter.com/2015/03/hart-xm3-barrel/Do a search for images of Hart barrel blanks, you'll find some more with the same layout. That 7 at the end of the bore measurement is offset and might represent something else other than .0007" plus .242.

Whatcha gonna make with it Jim?" 6mm Improved. I have a 700 long action that I bought from the fire that I am going to use. Next thing I think will be a mediumish sporter 6mm Creedmoor. You guys think its a 7 twist?
