HiCountry, I used a 150 grain Scirocco in my 7 mag on a mule deer, and I liked it's performance, but I dont have much experience with it other than that. I do believe it to be a good mule deer on down round, but I dont have Elk experience with it. I may get an opportunity to Elk hunt in Montana this year, and if I do, I will probably develop some loads for my 300 Win or the 7 mag. But I would go with a partition or X bullet if it shoots ok. I'm jealous of your 270 WSM, as a muley hunter, that just sounds like a sweet setup.
