Thread: Too fast and dangerous? 7mm Rem Mag, 180gr ELD-M, RL26

Hi Team,

I'm in need of some wisdom from the forum.
I have worked up a load for my 7RM that can shoot the hair off the nut of a fly at 100y (exaggerating a bit).
However the load is a lot faster than what the hornady reloading guide says. The test rifle from the book had a 2" shorter barrel and a slower 1:9 twist rate. Mines a suppressed 26" 1:8 twist.
From your wisdom, should I be concerned that my speed of 3070fps is a lot faster than what the book says I should be getting of 2900fps with a book max of 67.3gr of RL26?

Nosler Brass
Fed Match Mag Primers
Hornady ELD-M Projectiles
68gr of Reloader 26
COAL: 3.380
Average Speed: 3070fps (10 round test)
ES: 17fps (10 round test)
Average group size 0.27" (2x 5 round groups)

Primers are not showing signs of flattening, and no sticky bolt, a single case of 10 showed a faint extractor mark.

The load of 68gr is .7gr above hornady's book max which is at 67.3gr of Reloader 26.
The COAL of 3.380" is longer than the hornady COAL of 3.290.

I'm keen to hear what your thoughts are, should I be concerned and back off my load back to where the speed aligns with the book recommended speeds?
