Rifle Barrel Identification.

[LongestShot]

I've got two barreled actions; stamped at the base of the 1st barrel is "6.5x284 Norma (8)
On the second one is "6.5x284 Norma (8.5)

I'm assuming that the (8) and the (8.5) designates the rifling. Can anyone confirm?

Probably depend on the barrel manufacturer's marking style. I've measured actual twist on a couple of barrels that were not marked using similar method as below. https://www.google.com/search?sca_e...#fpstate=ive&vld=cid:9328fa5f,vid:cdoCNZBlRGQ

Any pictures to share?

Yep.
On about every barrel I've seen stamped that way…the parentheses usually indicates twist rate.

It probably is a 1:8" twist, but I do not want to assume anything. Usually, it is stamped on the breech end before it is chambered, and GS normally cuts ~1/8" off it.

You can always check it with a tight patched jag and record the 1 rotation and length of travel to get there.

One last question: How do I tell if this is a Mauser 98 action or a Mauser 96 action?

ADDITIONAL INFO!
I removed the stock; in very fine lettering it says, "Cole Harps ME".
I don't know if there was a rifle company in Maine, 50-60 years ago or what. There's a Harpswell Gun shop, but nothing else. Here's a couple Pics.

Supposedly the 96 will cock on closing and 98 cocks on opening?

 

[Bob Wright]

That's not a military pattern 96 or 98 I don't think. It looks like a sporter model pattern, post war Mauser. Everything is different except the flat bottom receiver.

Looking at the bolt shroud it looks like a Husqvarna/Carl Gustaf M9000. If it is one of those the bolt lugs will be a dovetail shape. Please see photos.
