The 6.5 CM. Is a lesser cartridge in every way. The only way to fairly compare them is with similar . Bullet characteristics The CM just isn't in the same league as a elk( elk are the baseline here) hunting round. Comparing these chamberings at 700 and 800 yards is just not practicle, these are high probability wounding distances, imo. 300 yards is a fairly long shot, many are cleanly missed or worse , wounded a lesser distances.My little old opinion
