Hornady ELD-Match 147gr

[Second]

[Sticks]

What are your uses? Seems a little too much for the Grendel to make an effective LR target round. I've had some promising results with the 130 ELDs in my Howa (been able to match Factory ELD ammo speeds) but are now out of stock everywhere I look.

For shooting in a bolt action Remington 700, you can certainly load the 147gr ELD-M if it will fit in your magazines, or if you are fine with single-loading.

Vihtavuori has data for 144gr Lapua FMJ. 2356fps was achieved with N540 from a 24" barrel, holding to SAAMI Maximum Average Pressure.

In the Remington 700, you could probably get up to 2500fps with that bullet, depending on the power used.

If you load to mag length, or to your Ogive (presuming it is in the 55.1 to 55.3mm ... I am trying to go off memory here) to your lands, then that will give you a fair bit more case capacity before compression.

The 130 ELDs I was getting into the 760 mps area (the 123 ELD I was getting north of 822 mps vs 757 factory ammo) out of my Howa with a 50.8 cm barrel. Just starting to get some flattening on the primers, still had a nice rounded edge, just not as much of a radius.

Gods I hope it was you that was initially posting in metric...

With the Hornady tool, I determined that my 147gr OAL at 0.020" from the lands is 2.345". That should fit nicely in a modified 10 round PRI 6.8 mag.

There is a trade off where the heavier can't keep up with the lighter performance. Since you are running a bolt, you might take a look at the 123 ELDs or the 120 Lapua. A G7 BC of .506 (Hornady) and you can get significantly higher speeds than possible in an AR or the factory ammo at SAMMI spec pressures.

What are you basing your MV on for the two bullets?

The speed for the 108gr is my own load in this rifle.
The speed for the 147gr is a ruff estimation. Have calculated on 2200 fps.

The published load data for the Vihtavouri powder have for the Grendel with a 144gr FMJ Lapua bullet, Lets say the N140 powder have a MAX speed of 2310 fps with this bullet.
I made a guess with a heavier bullet and setteled with 2200 fps. Might be way wrong but this is my guess.

In my rifle, a 20" Howa, I get good accuracy at a hair over 2600 fps with 123's. Any hotter would be hotter than I want to run them. The 147's will do 2350 or a bit more with AR Comp, which *I feel* is a comparable-ish pressure range. I'd have to run the numbers again, but I'm pretty sure they catch 123's in velocity well before 1,000 yards.

The 147gr will wait for future testing.
Have ordered some Hornady ELD-Match in 140gr that will be tested.
Will start a new thread for that so this thread is kept a little cleaner for the 147gr.

Here's what the 140gr AMAX looks like at different COL with cutaway to see the base location relative to the neck-shoulder junction:
