buying too much and confused the m&p pricing with the Sr762 pricing since I had been looking for a 308 for a while.

holding off so I can do a RPR I think.

RPR is a sweet rifle. Constantly hearing positive reviews. A couple of our snipers are running 6.5mm and 6mm RPRs as personal competition rifles. And these are guys who are issued AI AWs for duty rifles (.308). Probably the best bang for the buck in the precision rifle world.

6.5 for me. I don't have much of a reason behind it, other than to say the last time I was shooting long range with a buddy, he brought his RPR in 6.5. I watched him walk it all the way out to 1000 with ease. I was struggling a bit with my MK11 and he made it look so damn easy.

That sold it for me...ill get one eventually

6.5mm for me. The 6.5mm carries more energy downrange, and the bullets carry a higher BC. Federal/Vista Outdoor created a .260Rem cartridge for USASOC that matches the ballistics of .300Win Mag out to ~1600yds. It's not much different than what handloaders/reloaders do with custom competition loads.

I'm not against the 6mm, but it's much like the .243Win in that it's a faster bullet. The 6.5 will be between 2600-2900fps for factory ammo, depending on barrel length and bullet weight. The 6mm will be 2900-3150fps. The 6mm uses the same powder charge as a 6.5, with a 9% smaller bore. This will increase friction, and thus, increase wear. Early reports indicate that 6mm Creedmoor barrels are burning out in 1200-1500rds. 6.5CM barrels are pushing 2000-2500 average. Not a massive difference, but still worth noting. I've also read that the 6mm/.243 sometimes does not carry enough down range energy to make significant enough splash at longer ranges on steel for visual hit confirmation, as well as not being able to knock down some heavier steel targets that the 6.5s are knocking down or turning.

If you compare Hornady factory 6mm 108gr ELD Match vs 6.5mm 140gr ELD Match, they are very close ballistically.

Current environmentals at my house: Temp 34F, 932ft elev, 30.188Hg, 9.4mph wind

500yds:
6CM: 46.01" drop, 15.86" wind deflection at FULL VALUE (90°)
6.5: 53.55" drop, 14.53" wind

1000yds:
6CM: 296.85" drop, 76.80" wind
6.5: 324.53" drop, 68.17" wind

1200yds:
6CM: 501.62" drop, 119.52" wind
6.5: 533.73" drop, 104.68" wind

1375yds (1356yds 6CM goes transonic)
6CM: 766.05" drop, 166.66" wind
6.5: 793.48" drop, 144.77" wind

1500yds (1472yds 6.5mm goes transonic)
6CM: 1006.30" drop, 205.38" wind
6.5: 1024.50" drop, 177.95" wind

Basically, they're really similar. The 6mm is better at trajectory, but the 6.5mm is more resistant to wind deviation. If you pick up the wind, the wind drift increases dramatically.
I would pick the 6.5mm CM for the following reasons:
-Substantially more commercially available loads
-Substantially more commercially available match bullets
-Wider range of bullet weights to use from 120-147gr for long range (6mm/.264 typically only works with 90-108gr)
-More wind resistance to prevent drift (higher BC bullets)
-Longer barrel life
-Lower recoil
-More effective on medium and larger game like deer and elk (if you hunt)

This is just my personal opinion and what I would personally want. YMMV
