After owning 3 264's and many other 26 calibers over the last 20 years.

I'm not all that impressed with large powder volume 26 calibers.

I can pretty much mimic the same performance with a 7 mm Rem Mag and 120/140 grain bullets at 3,500/3,300 fps.
Especially if your large powder volume 6.5 rifle is a purposed flat-liner with no turrets.

For me, the high B.C. 6.5 caliber bullet is what does the work, not the powder volume.

The 6.5 bullets over-perform with less recoil, that's the beauty of shooting a 6.5/26 caliber rifle.

I wouldn't own a 6.5 rifle without being able to dial a turret for it as the 6.5 bullet is a natural for hang time.

60 grains approx of powder is about as much as I want to go in a 26 caliber rifle.

If anything, the 6.5 RCM/PRC has my attention.
