Why not just use Grendel mags in the AR?

I put about 700 75 v max down a 1 in 7 22-250 before it started blowing them up. Things change in the barrel as they go.
Exactly!
There are tons of bullets that can handle way more than 300k RPM. It's pretty easy to get 100 and shoot them and find out. 300k is just a rule of thumb and is going to be on the conservative side because it is a number provided by the bullet manufacturer. They aren't going to give a number that is borderline. They are always going to error on the side of bullets not blowing up just like they do with twist rates and stability.
Preach!!
I caught it verbally during their podcast video, the one about new products for 2024.
He said 1:10 out loud.
Their CS/Tech support folks will answer. I haven't had my hands on any yet so I can't say for certain.
ETA: At about 29:20

Tech response was pretty quick, confirmed 1:10 recommended.
I may buy a box and try in a 308 with 1:12 barrel and see what the target and true ballistics chrono tells me vs 178eldx which seems to have the highest BC other than the Atip in that weight class. Worst case they become varmint bullets for the 1:9 32 inch 300winmag.

Prob not worth it for all 9 of y’all
Do you know what COAL will be needed to load the ELD-VTs in a .308 Win?I guess there is a 30 caliber offering as well... 174 gr.
No details on BC or minimum twist yet. But the Hornady site says it's suitable for varmints 50 lbs and under. And of course match/target.
Can't really say I'm going to plunk down $40+ for a box of 30 cal bullets to blow up coyotes or woodchucks.That's a lot of powder and LR primers to do something that a .224 or 6mm option would do more efficiently.
Might breathe a little extra life into a .308 Win for LR target though.
I'm skeptically cautiously optimistic.

1:12" should work fine but you may run into issues if you're at low altitude and low temps (like Alaska in the winter). Most everyone should be fine running 1:12.
ETA: I'll double check our stability software tomorrow but I'm almost positive we shot them in 1:12" .308 barrels to verify and they shot fine. Going to recommend 1:10" for the sake of not having to question it but 1:12 should work for most people.
Where are the .22cals available!?
Thanks,
I'm Australian mainland, would be very unusual to ever shoot at higher air density than maybe 12 centigrade with some humidity near sea level. If I camped out in the mountains and shot in the morning it could be around freezing but you are talking near a kilometre of elevation. Primary use would be FTR or sporter class shooting 300-900 yards between 15 and 35 Celsius near sea level generally with reasonable humidity, otherwise a bit of pest shooting.
Will ask a favor for perspective, but when you run your internal model, can you also run a Miller just for comparison?
Cool. Interesting how the mass props change things.
Many thanks.
Merry Christmas and Happy New Year!
Hey, thanks a lot for all this info. Are you about to comment on the COAL that will be required to run the .308 ELD-VTs in a 308 Win? Happy new year
How's the 174gr handle pressure? I was thinking I'd put them in Fury brass and...

They don't quite make SAAMI, but nothing crazy, you can keep the ogive out of the case at 2.850 I'm pretty sure and if you have 2.950 AICS magazines you'll be in business.
Not sure. We've taken them up to ~65,000psi in .300 PRC's without issue, but I can't guess what a bonus 15,000psi would do. I've heard some stories about lead cores and super high pressures not being the best partners.
Just saw the 30cal 174gr, the BC is nuts. Anyone used it on medium game yet? I'll likely be getting rid of my 168gr TMKs in favor of the 174s. Will be perfect for the XM3.

Mine is bolt
There are 14 of us now shooting 20 cals. Come on man.Prob not worth it for all 9 of y’all
Well the 22cal 62 eldvt really splatters prairie rodents. Makes a real loud pop! 3340 fps out of my 20” 22 arc.
I have some 62 grain ELD VTs on the way. Would like to try them in a 1:8 22-250, what powder would be your powder of choice to start with?
I ended up with some 62s. I’m not sure how stable they are in an 8 twist 223. Had one round to errant, and enter 2” left of the group at an angle. The rest of the group was solid ~.8” for the remaining 9 shots. I’ll have to test a little at distance.
@Ledzep
Because you seem to be in the know, and I don’t know how, would it be possible for you to run a stability for the 62 eldvt out of an 8 twist at 2950 in say sub 1000ft density altitude?
I had one errant round on my 10 shot test group, looks like I went off path and entered paper at an angle, 2” off the remaining decent 9 rounds.

What muzzle device?
Gyro should be good. Any bullet in the 4 dof Library you can run the calc and in table view it shows you gyro.
G2 Ultra 7 6.5
I’m assuming that 1.5 or higher is still the bar you want to be above?
Thanks I appreciate it.
I'll use stuff in the 1.2-1.3 range, but yeah 1.5 + is optimal. Let me know if you see any more weird stuff.
