is anyone running a 175 eldx out of there 7 mag ? if so what powder and charge are you running and what kind of FPS are you getting. hornady book says H1000 with max should be around 2700 which i though was slow any help?
I stay back from max loads for several reasons. Keeping that in mind my load is 68.9gr H1000, fed 215, Norma brass, ... I forget my COAL, but that makes tiny little bughole groups waaaaayyyy the heck out there @~ 2850fps
Also what is the COAL shown for 175 ELD-X in the Hornady book?
Probably 3.340" or less, I have my rifle's barrel chambered to allow the 175/180 grain bullets to not have the shank of the bullet just above the boat tail to be below the neck shoulder junction of the case which allows for being able to use a little more powder safely.
You should always work up your load slowly watching for pressure signs, flattened primers, ejector marks, harder bolt lift/extraction etc.... , if you experience any of these signs you back down your powder charge, neither of the loads I use have any signs of high/max pressure.
It’s been stated above but the OAL for SAAMI spec 7 mag is short and it’s also not a 65k psi “magnum” like the 300 WM etc. so the reloading manual will be conservative because Hornady’s published loads were shot in a SAAMI spec pressure barrel.
