I personally don't think changing the chamber dimensions will effect the accuracy of the rifle. It will effect the load used to achieve best accuracy if anything. I have seated the 210, & 208 out much farther in my old brl with the same results.
Don't know what you're asking about #3. Those specs are with the 230 Hyb TGT in my rifle.
