Has anyone had trouble using 308 pmags in 6.5 creedmoore AR10 pattern rifles?

Nope. My only problems have been tuning the gas system so it works correctly

No problem.
Why do you ask?

They're the only mags I've ever used for my .308 and 6.5 ARs. Never had a single problem.

The question was born out of naivety And I couldnt find many definitive answers online.  I have ARs in 308 and am just getting into the 6.5 game.

I've not had any problem with mine, 308 P-Mags are all I own for my 6.5.

6.5 Creedmoor based on the 308 case, so the 308 mags work perfectly fine.

I have never had any issues with factory ammo, but there are some that have longer internal dimensions for longer oal if you reload.
I believe Lancers have the most internal length that will let you feed longer rounds.

Nonissues with any, including handload, ammo,  this in an aero lower.

Are these AR-10s that hard to tune? I didn't spend more than one range trip to do this.

The only issue I have had is plastic being slightly thicker than metal, you do lose a little room for longer OAL rounds

I think Magpul makes a different version of the mag specifically for that reason.

Not at all difficult. Took me four rounds to set the gas block on my 6.5 and ten rounds for the adjustable carrier on my .308. Haven't touched either in years.

They work well for my 6.5 Manbun rifles.

Correct. M118LR magazines permit a round with longer OAL.
