Thread: 7mmRM project

Quickload is a windows program it's just a prediction but can be tuned to be quite accurate.
Results for ADI max charges using 162 eld-x instead of 162 spbt 22in barrel, your 63.5 OAL and default case capacity
ADI 2213 64Gr 2846 FPS 97% Burnt
ADI 2217 70Gr 2907 FPS 99% Burnt
ADI 2225 73.5Gr 2964 FPS 100% Burnt (109.7% fill)

Hey that real handy mate. The burn rate... is it optimal/recommended 100%? I’m guessing that means that powder has fully burnt prior to leaving the barrel...? Cheers

I see the point of confusion here I typed 63.5 OAL where in fact I used 85.0 OAL as stated in your first post. I was looking at the "case length' when i typed it.
Sorry for the mix up

All good mate, yeah that fully confused me lol.(as you can see by the posts)

Half my fault as well, probably used the wrong terms?

WB marker test (average of 5 dummy rounds) shows
87mm OAL - projectile pressed into dummy case.

CaseOAL on left over cases from prev owner were was set at 85mm. However these were AMAX, not ELDX. Pretty similar though.

The 90+ measurement above included the comparator I believe. (So disregard)
Comparator measurement was 68mm. With 83.6 COAL it would read 66.6mm

Can we use OAL of 87mm and see what the recommended seating depth is for ELDX? Or is 83.6 default from the book?

I have a funny feeling that COAL 85mm is probably sound, I’m just trying to get my head around “the reason why?” rather than using old data.

Feedback welcome.

Cheers
