I am in love. If I ever build a long-barreled Grendel it'll look something like this. VERY nice. What ammo load were you using in the video?

[pestilence]

Thanks very much. That's factory Hornady match 123gr A-Max. I have all the stuff for reloading Grendel, but that ammo shoots so nice, I haven't ever loaded a round and just bought 400 more rounds

[Whelenon]

Obviously, you've done your homework, very nice. Must be a pleasure to shoot, well done.

Very nice. What tripod is that?

[bwaites]

Very nice. What tripod is that?

Guessing that its a Manfrotto, am I right?

[MedicMan218]

Did you get your barrel from MidwayUSA?
Also, what is the twist on your barrel and is its actually 6.5G or .264LBC?

[pestilence]

Guessing that its a Manfrotto, am I right?

Correct. It's a Manfrotto 55 series with a 322RC2 grip action ball head and a hog saddle.

Yes, it's stamped 6.5 Grendel, it's 1:8.75" twist, and I got it from Midway.

Hah, not really, it's got a different upper, a different lower, a different rail, a different bipod, and a different scope from what it started with. But yeah, it's always been an absolute joy.

20"er? very nice!

[pestilence]

20"er? very nice!

Aye - 20". Thanks

The only thing that could make that better is the GG&G GS-1 20MOA riser/scout rail I've got collecting dust in my basement.

Seriously, though, I'm in the process of building something similar right now. Good stuff.

Yeah I went with the riser I used because it was long enough to bridge the receiver and forearm rails for a long distance and increase the stiffness of the whole chassis. I wanted to reduce flex as much as possible to run the bipod far out front to reduce the travel of the muzzle when I interfered with the butt. I've got 10MOA in the mount I have, and the TRMR2 reticle has something like 30 mils of holdover scale when you zoom it out, so holdover isn't really an issue.

Very nice stick! I love the looks! I also like your choice of can (biased of course-- I run the same can on the older 18 tooth mount).

Have you fired any groups from that tripod? I've never used a tripod like that with an accuracy rig, and I'm curious how well it performs/ease of use wise.

Thanks very much. I still catch myself ogling pictures of it even when it's sitting in a safe nearby

I have actually not taken the tripod out shooting yet. I just got it put together and was not able to go out this weekend. I'll be testing it next weekend for sure. I'll come back here and post the results.
