Thread: 7mm mag and 180gr ELDM

Thanks. Hopefully he will chime in. I actually asked Greg first off if he'd like to take on this job, though it wasn't to be

What im most interested in is -

7mm RM with 180gr ELDM. COAL, Powder charge, Velocity, and barrel length.
The achilles heel of the 7RM (that I can see) is that with most actions/mags (SAAMI 7mm RM spec in general) you need to seat the projectile really deep into the case in order to fit it, which takes up capacity thus reducing velocity. (not to mention factory twist rates generally not suited to the heavies)

So im interested in COAL as that dictates how much powder you can cram in the case, then velocity & barrel length in relation to this.

My thinking is ill have more capacity to play with than most people would, as I can seat projectiles out further than most due to the large action thus less reduction in case capacity for powder. Combined with the long barrel I think ill be close. (quick load predicts ill get above 3000fps with relative ease)
I would prefer 3000fps and the ease of dealing with the run of the mill 7RM cartridge, than I would 3150fps and have to deal with expensive & hard to find brass etc.

I appreciate everyone's input. Its most interesting
