With apologies to the Horde, I will rerun the charts when time permits.
In the meantime, here are the correct #'s for the 123 Scenar, using Brian Litz's measured .265 G7 bc.
Good catch, K1dude.

I thought this forum was about the 6.5 Grendel or 7.62x39 variants not 6.8 SPC variants.
So, yes, this forum is a happy place for the discussion.shootersnotes.com

Again, allow me to apologize to the Horde for sloppy spreadsheeting.
Bad news: Once home, I confirmed via the saved header data in the parent spreadsheet that the data was, in fact, from the 136 ScenarL and its .288 BC.
Good news: Even with the 123 Scenar and its .265 BC, the picture changes little. While the 22V has a slightly larger advantage on drop / drift, the energy still eludes it, even out to 1000.

I have not read all of the comments and apologize for any redundancy, looking at the 224V the comparison to anything other than another 224V is inconceivable. You may try individual comparisons of all components, the cartridge, bullet, powder, primer, firearm and test environment. At best you are painting a lemon green and calling it a lime. Remember Popeye "I ams what I ams"

The 75 gr Berger VLD has a G7 of 0.217. 2900 fps is what I get with 27 gr of XBR out of an 18" - which Hodgdon just published as its max charge for 75s - they have it at 2969 out of a 24. But they have it at 3049 with H4350. Who woulda thunk. H4350 in 22 Nosler. Nosler didn't even think of it!Let's go Brandon!

I originally got a 6.5 Grendel because I considered 223 to be too small for deer.
I know many have been killed with 22 caliber but it just seems too small.
I would say based on this information the 224 Valkyrie is better than the 6.5 Grendel for ringing steel at long range.

It might well be, but I consider this cartridge to be still in the Marketing Hype Phase. Need about a year for a consensus on real-world performance.
For pure long-range ballistics within the confines of the standard AR double-stack magazine and mag well, we've already had the 6mmAR, for example.
6.5 Grendel has its place doing many things very well, without needing to absolutely specialize in any one thing. It's like the F/A-18 Hornet. Damn good multi-role weapon.
We've got 85-grain varmint bullets for prairie dogs; 140-grain bullets for moose (about the same as traditional 6.5 Swedish). And all the other bullets and applications in-between. If I could have only ONE gun. . . .
I challenge Federal's lofty claims that 224 Valkyrie is the best MSR cartridge EVER. If the AK47 with a 123-grain bullet was good enough to serve the world's militaries for — what, 70 years? — the 6.5 Grendel with a 123-grain sure as hell is good enough. And that's without hardly trying to develop specialized projectiles. So 6.5 Grendel is still the best MSR cartridge EVER. Of this I have no doubt.
Plus, we've got cheap Wolf steel-case by the pallet-load.
Having said that, 224 Valkyrie still has my seal of approval, for all the reasons I've mentioned earlier in this thread. Probably should have been based on the Grendel case for even better performance, but it's a solid design in its own right. Put it this way: It's what the 6.8 SPC should have been.:: 6.5 GRENDEL Deer and Targets :: 6mmARC Targets and Varmints and Deer :: 22 ARC Varmints and Targets

What BFT said. It's going to be a few weeks, but I'm going to pick up either some 90 gr SMKs or Bergers and single load them in my 22 Nosler with an OAL of 2.46 per the new Hodgdon data with H4350. I should be able to get close to 2700 based on the velocities they publish for other loads I've tried.
One thing is Sierra says the 90s need a twist of 1:6.5 and Berger says 1:6 for the VLDs and my 22N is 1:8. If a 224V barrel is optimized for 90s, it's going to make it a bit of a one trick pony since lighter bullets won't be able to handle the twist. Nothing wrong with that as I did a 1:7 on the 6mm Grrrrr barrel I ordered to stabilize the heavies at the expense of the lites, but the 224V will be even more magnified. There's a reason why there's a market for 1:14 22-250s.
Like BFT said, Grrrrr can do everythingLet's go Brandon!

In my original analysis, I opined that if the 224V uses widely available, standard 1:7 barrels, it would be a hit.
If it requires a non-standard barrel blank, I think its appeal will be more limited. Despite the constant innovation, the firearms industry is quite hide-bound, when it comes right down to it.:: 6.5 GRENDEL Deer and Targets :: 6mmARC Targets and Varmints and Deer :: 22 ARC Varmints and Targets
