444 Shooter, The 270 150g SST is listed at 2600 to 3200 (same as the interlock) but Don't use those veleocity ranges as all end all be all, they realy don't mean that much. You WILL get HIGLY explosive preformance at 3200 from an SST.
I currently am using a 162 SST at ~2900 from a 7mag as my big buck load. It gives big expansion with great penetration at the type of range I will be shooting (1 yard to 400
) It will penetrate 3/4 of a deer on a quartering shot and give an entrance hole you can measure in inches. Your 270wsm with a 150g SST would pretty much duplicate my load and performance "should" be about the same.
I would not recommend a low SD SST at high velocity, the initatal explosion of the bullet leaves nothing left and penetration is at a very real risk of being poor for bad angle shots. The high SD SST (2.8 ish or greater) are the only way to go. I also believe this to be true with Nosler Balistic Tips. After that initial expansion you need some bullet left to make sure the job gets done all the way through.
