Thanks guys. I guess I wasn't worried about the bullet not killing the does, and should have explained myself better. My concern was that the bullet might be too though on a ribs shot and not expand enough for a quick kill meaning waaaay overpenetrate...
But I guess it seems it will be fine enough.
My only 2 other animals a pronghorn and a mulen deer were shot with the same gun, the goat with the same weight Partition (DRT) and the mule deer with a 150 Winchester CT - which I think is a ballistic tip... both did the trick.
My plan with the SGKS was just as GSSP said, to develop a load and transition to the PT's... will experiment and see if it is necessary, since I do want to eat them.
