I have shot deer with the 7mmRM and 162 gr Hornady SST. [I think that is what you meant.]
That pic is of my first 7mmRM and now I have a reamer and have built 3 more 7mmRM rifles.
Belted magnum brass does not work well with multiple rifles.
Get the brass new and segregate it to one rifle.
Alternatively, the Innovative Technologies die is supposed to make them compatible, I have one, but I still want the brass segregated to each rifle.
I like to FL resize the brass and push back the shoulder .001".
When i chamber them, I headspace at .215", not the SAAMI sloppy .220" like factory rifles.
