The 6.5 Creed shoots similar bullet weights as 270 (which is 6.8mm) about 100-150 fps slower at the muzzle, but at around 200 yards or farther the better 6.5 bullets are faster than 270.
Not true, but nice try!
129 grain SST 6.5 CM vs. 130 grain SST .270 Win Hornady Superformance ammunition, .270 Win is nearly 200 fps faster at 500 yards.
129 grain IB 6.5 CM vs. 130 grain IB .270 Hornady Whitetail, .270 is over 100 fps faster at 500 yards.
Federal Premium 140 grain Nosler Accubond both in 6.5 CM and .270 Win, .270 still 100+ fps faster at 500.
6.5 Creedmoor is a great round, but it isn't going to give the average deer hunter much advantage over the .270 Win.
