Hornady ELD-Match 140gr

[LRRPF52]

N540 will give you the most speed, being a double energy based powder. Not sure how temp stable it is.

I used to use it in .260 Rem, and destroyed several firing pin retaining pins in the process on my large frame .260 Rem gas gun.

Hit some pretty crazy speeds in the summer.

I don't see any load data for N160.

You're a little over Vihtavuori book data with the 139gr Scenar, which is the closest bullet to the 140gr AMAX.

[CastleBravo]

QuickLOAD predicts 28gr of N140 under a 140 ELD-M loaded to 2.417" will yield 2338 fps or 712 m/s (pretty close to your speed) from a 20" tube with a Pmax of 54,279 psi. OBT theory predicts an accuracy node around 1.185 ms, which QL says happens at ~2,304 fps (~702 m/s) with N140.

The same OBT node with your Norma 203B is predicted to be somewhere around 28.4 gr of powder for 2,351 fps (712 m/s), and with just 51,000 psi. If you are OK with more heavily compressed charges, QL also says ~30.9gr of RL17/Elcho17 hits the same OBT node at 2380 fps (725 m/s), with less than 48,000 psi.

WARNING: these numbers are from a computer simulation, and are not to be trusted as actual load data (ALWAYS WORK UP!). Also, I ran those numbers with a 2.417" COAL, so trying to duplicate those loads at SAAMI mag length would be even more dangerous.

Thanks CastleBravo!

Feels that I might be in the right load now. Have just finnished the load on 27,6gr, 27,7gr, 27,8gr and 27,9gr. 5 shots each load.

Went to the range this morning and shot the 4 different loads.
5 shots per load, prone position and 100 meters distance.

I shot 4 groups and all of them were really good.
After the shooting the numbers were also good.

Load: 27,6gr
Avg: 704 mps
SD: 5
ES: 13

Load: 27,7gr
Avg: 706 mps
SD: 2
ES: 5

Load: 27,8gr
Avg: 707 mps
SD: 2
ES: 7
IMG_2188.JPG

Load: 27,9
Avg. 707 mps
SD: 2
ES: 5

When I added the three highest loads (27,7-27,9gr) the numbers were:
Avg: 707
SD: 2
ES: 7

So If I pick the load 27,8gr of N140 I think this will be a good one.

[Sticks]

Wow. You could probably load up on a progressive with that .3 grain spread getting the same speed. Nice.

[jason miller]

Nice shooting! And nice rifle.

I don't know much about VV powders, but some others have pushed 140 grain bullets over 2400 fps with no obvious signs of over-pressure in my 20" Howa- if you felt like trying to push further.

Second.

They are if you shoot them from an AR-15. You have to seat them so they fit the magazine, and this means the bullets need to be pretty deep in the case. Thus taking up powder space.

Also, hot loading a Grendel in an AR-15 is risky. Not a problem in your Remington or most other bolt rifles. Much bigger problem with a AR-15.

Yes. The COAL in the AR-15 is also what Ive read the limiter.
Didn’t ment to affend the AR-15 community, we are a bit outnoumbered with our boltaction Grendels

Second:

There isn't any sort of conflict on the Grendel Forum between gas and bolt gunners so don't even let such a notion enter your mind.

I doubt anyone here cares what type of rifle one uses.

You've have some awesome results with both the SST and the ELDs. Since you are running bolt action, I don't wonder if you could try to get to the next velocity node.

My quick tests with the 123 ELD and 130 ELD out of my Howa were getting into the upper 2600s on the 123s and 2500s on the 130s. The 130s were showing real promise, but alas, I can not find them anywhere now.

Isn't that the way it goes? Just when you find the worm hole in the universe that gets you just where you want to be and poof, it goes away!

I have downloaded a chart from lngunowners.com that shows the 142 SMK as the bench mark for down range retained energy. Only the 123 gr SMK could stay close. The 123r started out T 105% of the 142 gr, but at 500 yards it crossed over and fell off out to 1100 yrs where its retained energy was at 89% of the 142 gr SMK. Drama, Drama, Drama!
