To me, I really don't see much of a difference. If you're stuck shooting factory ammo, the 6 CM is your obvious answer. Otherwise, pick one and go with it.

I went with the 6 CM and it's been great.

I was on the fence between 6CM and 6GT and went 6GT on my CTR rebarrel. I like the better barrel life of the 6GT and it hits a sweet spot between 6ARC and 6CM. My goal is to shoot 108 ELDMs over Varget out of a 20" suppressed barrel for about 2800-2850 FPS. That should deliver terminal velocities out to 700 yards. More than enough range I plan on shooting at game.

If CTR mags dont feed reliably, I've heard the 3 round Tikka M mag feeds 6GT great. I will just throw my CTR in an Echo chassis and get a mag retention spring.

@General RE LEE I would think it would work from ctr mags. If not I’ve had good luck with the M mags and my 22GT.

I’ve often contemplated buying a 6GT prefit, but think I’ll just do a short barrel 6.5 creed for the rare times I need more than 22. Let us know how that GT shoots, I’ve thoroughly enjoyed the 22 tiger, looking fwd to using it some more this coming fall.

Alright I’m looking at building either a 6mm creedmoor or 6mm gt for the daughters first hunting rifle. Only reason I’m not looking at 243 is it seems these other two are easier to find brass anymore. So let’s hear the pros and cons of the 6mm creedmoor vs the 6mm gt. Will be a short barrel build no longer than 20” and being ran suppressed
6CM will give you more impact velocity with the shorter barrel than the GT. Barrel life is the only advantage the GT has, IMO.
