6.5 Grendel Max

[s3silver]

That AI is a grendel necked down to 6mm. Pushing berger 105's at.2850.

That's what I thought. That lighting sure is deceptive...

[s3silver]

Another 100 fps with 123's would be nice indeed! Or the same velocity with 130's for us hunters. I was hoping some super powder would suffice... But if I'll have to keep my eye on this thread to see where the G Max goes.

I agree. Guess we're all waiting for a report from sneaky on.

Starting to dig into this- does anyone here have a 6.8 magazine--- both- metal, & plastic versions would be nice--- to measure from? OAL internal length - using calipers?

[s3silver]

Wish I did. Are you hoping to get a little more oal with it?

[sneaky one]

Yes, S3- I read a while back-- that 1-2 guys on here are using the 6.8 mags. Been busy at work last weeks. Sorry for the delayed response.

Sneaky, any update on the AR variant of the Grendel Max?

[sneaky one]

Sorry, not much to report. Wife had me drop that idea like a handful of boiling water- so I could focus on the home remodeling projects.


I do know that it will be most beneficial to the bullets we use that have a short jump to rifling- 95 Vmax, my tweaked GMX pills, .etc...

If your mag won't let you load 38-50 K longer, meh...

I have some new bullets from Makers- the T Rex in 95 grn. LFP's. And some Lehigh controlled Chaos LFP's in 110 grn. all chamber a bit short.

I know 2 local prototype machinists that could tweak my dies for an in -between shoulder angle , between the Saamie and the AI. Then the idea of 40K ahead, for the AR only. My thinking was, - Practice with std loads, then get ready for hunt season and use the hotter items. All while fireforming some brass for the future.

I know the bolt is the weakest link, but only a few warm rounds per year will be fine .

My hunt pal blade 2 is building an AR in Grrr, and a boltie in CZ giuze. It's an AK unit- he likes it a ton, but I convinced him to re-barrel it to the mighty Grrr, max.

Or Max lite. Then we could share hunting ammo if the need arises. That's all I have for now.

The good thing about the Grendel-Max is I can utilize standard Grendel Dies although I have Wilson straight lines seating die which I am sure helps with the accuracy. When you start with the AI or altered shoulder age you will have to look at custom dies. I could load for my Grendel-Max and a standard Grendel with the same set of dies with just a seperate shell holder for each which is the most practical way to go as far as I can see.

so, how much more velocity did you eck out and what was the increase in recoil?
