6 vs 6.5 Creedmoor opinions wanted

[7.62 Gunner]

I like the velocity of the 6, but the barrel life and larger bullets of the 6.5 Creedmoor.

Basically, I want a super low recoil gun that maintains 1800 fps at ~700 yards with 800-1200 ft lbs of energy at 700 yds.

Lots of people are blowing up the 22 Creedmoor, but let's just say I'm not bought in!

My other thoughts are 25-06 Ackley, 6mm Rem Ackley and 243 Ackley, but I like the simplicity of the Creedmoor. Call it the easy button.

So, between the 6 and 6.5, it seems like a barrel life question mostly, or is there something else. I'd like max barrel life as I will shoot this a lot.

Is there something else to consider? No, I don't want a big gun….i want to shoot a lot. No, I don't want a trainer!

I shot a match with a guy this summer who had 1800 rounds on his 6 creed and was still cloverleafing. If you chase speed though you'll be lucky to break 1200.
I'd do a 25 creed personally but the 6 is solid too
