6mm Creedmoor

With all the reading I've done on 6mm cm, when comparing its impact on the shooting world to its 6.5 brother, you are looking at overwhelming (6.5) and underwhelming (6mm). 6mm hasn't even come close to popularity levels of the 6.5.  I would not trade/replace my .243 with something so very similar as the 6mm cm. I also would not consider trade/replace of either of my 6.5cm, but at the same time, as a mostly deer hunter, if I could do it all over again, I'd no doubt settle on the veritable .270 Winchester. 

Yes I'm older and  have owned a great many calibers from the 22 centerfires up to and including .338.  Most of all, I miss my model 70 .270 with the laminated stock from the late 80's that Mike Palazzo accurized.  Fine shooter I will always regret having parted with.

It really depends on bullet selection.   In the smaller weight bullets, say 80gr range, the 6mm CM, 243, and 6mm Rem are within 100fps of each other (obviously barrel length is a factor in comparing).   The 240 Wby and 243 WSSM are 100fps faster than those 3 cartridges, in that weight range.  The 24 Nosler is 300-400fps faster in that weight range.


Where the 6mm CM shines is in the longer heavier bullets 115gr VLD and 101gr Hammer Hunter, and both companies recommend a 1:7 twist rate on the barrel for those.

Seems to be plenty of factory rounds on the shelf, specs look good.

IMO, if you're shooting factory ammo and you want a .243/6mm the 6mm CM is going to be your best option.  Hornady has done a really good job with making factory ammo for the 6 & 6.5 CM that shoots very well in most factory guns.  They've done the same thing with the 6.5PRC as well.

To say one is better than the other (6mm cm vs. .243 win), would be splitting hairs. 

yup
Really can’t say any cartridge is better than any other because it depends on the consumers needs and wants.

Bingo!
