As I research this more, I see that there's more to it that initially thought. Anyway, my initial goal was to chamber a barrel for a bolt action. Since my initial post I have talked with a reamer maker who has explained most of it to me. I also discovered my usual gunsmith is interested in putting together an AR 15 for himself. We have more to discuss.

If someone is wanting a 6.5 Grendel barrel for their AR15 I highly recommend Lothar Walther in Atlanta, Georgia. They make what they call a 6.5mm barrel or 6.5 CSS barrel. CSS is a website and company they own. They are the same exact chamber (actually the original as they really drew up the chamber and then the reamer)as the 6.5 Grendel. In fact they made the first 6.5 Grendel barrel, but then there was a dispute over the contract and LW dumped AA company. I know the guys that did all this at Lothar Walther and dumb your gunsmith knows more about it then I do. There were two original different chambers. The only difference being the neck area of the chambers. The standard chamber has the .300 neck and the other chamber has a .295 neck. Sometimes the .295 chamber was considered a match chamber, but actually it's not. The neck was tighter to preserve the brass longer. Both chambers have a multi angle throat. The LW barrel specs were originally a .2639 groove, .256 bore, right hand twist of 1 in 8 twist, button rifled. The barrels come with a 7.62x39 bolt and are head spaced for that. The AA bolts have a .011 deeper face cut that prevents them from being interchangeable without proper re head spacing. I won't get into why. If I can help with anything else let me know. I can put you in touch with the man to talk to at Lothar Walther.

That's all there is to it. It's an excellent little cartridge. It's really designed to shoot a 6.5 bullet in the 120 to 130 grain class.

Thanks

Thanks Joe. I have quoted some of what you wrote so that I can focus the issues that I ask for clarification. This CSS chamber, is it the same as the original 6.5 Grendel, if so which original? And I'm wondering if the LW still uses the same bore, groove and twist rate?

I'm also wondering is you had a misspelled word or something when you referred to my dumb gunsmith. I didn't think you knew the dumb SOB?

I'm still researching, so I don't yet know if a twist rate other than 1 in 8 is more suitable or not. You have confirmed some of the information I obtained from the reamer maker, and from my dumb gunsmith. I still have many questions, but since my gunsmith is putting together one for himself, and he ain't too smart, I'll talk him into experimenting with his assembly, and when he's got it down, mayby he can assemble one for me too.

Heck, he could swap out the parts, and I probably wouldn't know the difference.

The 6.5x39 improved (or whatever name it goes by) seems like a fun cartridge to me. I never did have much use for a 223 as it seems like a great cartridge for wounding deer to me.

Also, it seems like making the Grendel specs proprietary was a mistake, if that's what happened, which probably assured the success of the 6.8mm SPC. If so that's a shame.

Thanks again,
