Nice looking rifle, deere2320. Looks like you're on a roll.

Thank you Sir.

I have sized and fired 4 rounds so far so I could get my sizing dies set up. Scope should be here this week can't wait to start shooting it.

I've never lock-tited ring screws, but I had an Aero mount like that one and the ring screws kept backing out on it so you may want to bear that in mind. It was on a 5.56 AR with a 6X SWFA SS, so it was a light kicking rifle with a fairly heavy scope. Not knocking Aero's stuff (got their upper and lower), just my experience with that mount.
Running Burris med. tacticals now.



Let us know how that Black Hole Barrel shoots!

I will definitely let you know about the Blackhole Weaponry barrel. Thanks for the heads up on the mount but I already have alot of them and have never had any issue with mine but I always torque them.

Scope finally came now I can get to shooting this thing!

Great looking gun. Nice shooting!

Very nice!

Nice build. What sort of velocities would you expect with the heavier 6mm projectiles? How heavy can the round go at mag length?

Thanks guys. I know alot of guys run the 87gr and I believe they run a little heavier. The guy to ask is the fellow who developed the round his name is Ritch Johnson look him up under Ritch's Precision guns he can save you money on Blackhole Weaponry barrel's and a super guy to talk to.

I use the ch4d die set it is a straight neck down one pass through the dies and you're ready to seat the bullet. There's guys that are killing antelopes with it at 650 yards.

^^^^^^ I use the same dies as well.

My son shot his 1st nice Antelope buck at 515 yards last week with my 6x6.8

What bullet is the big game answer for this to fit mag length

A 90 grn ballistic tip would be AWSOME on blacktail at 2800 FPS

I'm not sure as of now just using the 58gr at this time but I am sure 5spd could answer that one.

In the AR15 I ran every bullet at 2.250" including the 90 &95g weights.
In my Savage 6x6.8 the col on all bullets is 2.290"
Yes the 90g NHBT is as good/accurate as the 95g NHBT.

Deere2320 if you have any 55g bullets give them a try also, same powder load works on them.

FWIW I just stumbled across a load note last night, 27.0 benchmark, and 85 tsx in the 6x6.8 in a shilen tube shot .5 moa give or take....

Verify that load in other data to make sure my note was not wrong, but it shot well enough that it was the first and last load I"ve ever tried in mine...

If I ever shoot the gun out of ammo, I"ll be trying 80 ttsx instead, but the 85s have done extremely well, 150 plus pound deer I've shot lengthwise trying to catch the bullet and never have....

What kind of speeds can be expected from 80-90gr bullets in a typical 20-22" AR in this chambering?
