These were on sale at Midway a few years ago, I should have bought them all!  In my 25-06 I use them with IMR 4064, great groups.  I think I killed a few groundhogs, but I don't remember anything about bullet performance.  (75 g V-max is my groundhog bullet, now.) 
I took the 90 grain Sierras deer hunting, but didn't shoot anything.
There was some debate if they were varmint or deer bullets.  I don't know, but they are very accurate.
