6mm CM

Wolverine lists a Ruger American in 6mm CM in stock. That would be a tough decision for me as the .243 version of the American comes with a 1:9 barrel so handles the longer hunting bullets fine. The magazines offer enough room to jam the bullets into the lands as well, you can play around with COAL to get the right balance and access the extra powder capacity easily. It's probably the one rifle that makes the least sense to offer in 6mm CM as a result, but at least the option is there.

Ah the 6.5 Creedmoor. Thanks gatehouse
 
Ruger and Savage are the only 6mm CM available I can find in Canada, Savage at Cabela's is a heavy barrel, Ruger is the less then stellar American version.
I have the Savage and it shoots fine, going to fill the lightweight hollow butt with wheel weights and silicone today I think to balance it out better, way to front heavy...
So if availably and options are a concern, 243 is way ahead lol.
 
Some guys shoot 6.5 Rem Mags to make believe they have a 6.5 PRC, some guys shoot 243 pretending they're a 6mm Creed haha
 
The biggest pain in the ass with the 6cm and PRC is Lee does not make a case length trimmer yet, have to do it the old fashioned way on my bench mounted lathe type trimmer, which I hate using for volume shooting.

Lee does make a 6.5 PRC trimmer now (91533). Plus they have quick trim dies for both calibers if you’re into that system.

Well....the Remington will fit in a short action with 2.800 OAL, the PRC claims to be made for short actions but not many will accom the 3.000 OAL. Even my factory PRC came in long action form, which I was glad to see.

Litz tested the G1 BC of the 90gr Accubond @ .355, the minimum impact speed for expansion as per Nosler is 1800 fps. The Barnes BC is .436 G1 and Barnes claims minimum speed is 1700 fps



The 243 has 4% more case capacity than a 6mm Creedmoor. That is before a bullet is seated. When both are loaded to 2.8" OAL with a 103gr ELDx bullet, the net case capacity of the 243 is 1% more. That will give around 8 fps more velocity when both are loaded to the same pressures/powders

Hence why I added, "all else being equal". - dan
