CRS, problem is, I'm sort of changing away from a load I have shot the crap out (and that works really well) and messing with something else... and it's messing with my head
You said a mouthful there. Life would be so much easier for all of loonies if we would quit messing with things that work.
I would shoot the Sierra, just don't think you need a partition for deer. If you were going to hunt elk, then I would step up to the partition.
