180 or 162 ELD-M 7mm Rem Mag?

Hi all,

I am in the early stages of load work up for a new rifle, a 7mm Rem Mag with a 26”, 1:9” twist barrel (Christensen Mesa LR).

It shows a lot of promise, but I am having trouble deciding which bullet to focus on. The edition of Nathan’s Cartridges book that I have mentions looking forward to the 180, and I have hear good things.

But, the accuracy node for the 180 in my rifle is looking to be around 2830-2860 FPS with H1000, which is the powder of most like to use due to temp stability and the fact I have a good bit of it on hand. I have a little RL26, but further supply of it is uncertain right now. There’s plenty of room for more speed, but accuracy definitely falls away above 2860 FPS.

On the other hand, I’ve found good accuracy nodes at 3090 and 3000 (with very good accuracy at the lower node).

I hunt whitetail deer, 0-700 yards.

Does the 180 show enough terminal performance gains to outweigh the velocity loss vs. the 162?

With the 162 at 3090, I have impact velocities of 2600 FPS or greater out to nearly 400 yards, which covers the majority of my shots on game.

Please overlook the typos, I can’t find any way to edit the post.

Hi Jonathan:

No worries on the typos, I like to blame them on my big thumbs (I usually use a phone).

At that speed with the 180gr bullet you are good to go for longer than your expected ranges. The higher BC of the 180gr bullet retains more speed and goes further. The 162gr also has enough juice for the ranges you are looking at shooting at.

For deer and elk the 162gr is more than enough, but if you lilke heavier bullets then go with the 180gr.

In this case I would pick the bullet that is more accurate in your rifle. Again, both will get the job done. Now if they are both equally accurate then I'd go with the 180gr.

Hope this helps and stay safe.

Hi Jonathan, 2800 to 2860fps is the norm. Base your decision on accuracy and also expected body weights. Here is a video which also includes some 7mm Rem Mag footage:
