I'd rather use 160's in the 7mm rem mag personally, but I have a schidt ton of 150gr partitions I bought when they were cheap at SPS. I also like and use the 162gr Hornady BTSP interlock in the old 7mm. Made my longest 1 shot kill on a buck with that bullet. The 162 ELDX also works. I use 150's in my 7mm08 and it likes them. To me the Rem mag can sling them faster, you might as well be using 160 class/weight bullets, unless you have a stockpile of 150's like some of us do..
