G'Day Fella's,

Jabali, sorry I don't have any experience with the heavier bullets in the 7mm Rem Mag.

I usually only shoot 120gr Nosler B/Tips and Barnes X that I have Moly coated. I also Moly treated the barrel with the treatment available from Brownell's in an attempt to squeeze more velocity out of this combination. They chronograph in at 3450fps out of my 24" Win Mod 70 Classic (All-Terrain, stainless). They shoot into sub MOA groups and were what I call "Maximum Safe Working Load" (MSWL), in this rifle.

If I remember correctly, for heavier bullets Reloader 22 and 25 may be "The Powders" to use for this cartridge.

Hope this helps.
