The 8 requirements are so that like temperature stable powders are used, same length barrels, similar construction hunting bullets are used because we are talking about hunting not punching holes in paper and sighting them in both at 3" high at 100 yards which one does to get a good 300 yard trajectory that can be used out to 350 yards by holding on the backbone of a deer sized animal. In a previous post you said how the 6.5 CM was better than the .270 because the long high b.c. bullets allowed better shot placement. I have shown you that you are are not correct because the .270 has a much better maximum point blank range as well as less wind drift (often) with the newer good b.c. medium weight projectiles in .270, up to normal hunting distances, say 350 yards. Furthermore the .270 has 10% better cross-sectional area for a larger wound channel. Why don't you have enough integrity to acknowledge that this is correct?
