I used the search feature here on the website, but did not really find a good answer
to my question.

Has anybody used the Gen 3 SR/LR M110 style Pmags in LaRue's large frame AR-10
lowers & had good luck? I have 3 of his mags on order & would love to be
able to afford more, but I can swing a couple of Pmags for sure...

The caliber I am using is 6.5 Creedmoor, and any thoughts on that rounds function
thru a Pmag made for 7.62x51 would also be appreciated :)

Thanks in advance :)

(Edited to add the 6.5 Creedmoor question)

While limited to 10-rounders in my f'd up state, ALL I use in my LaRue OBR 762 are pmags....they've never given me a moment of trouble.  Feed perfectly, with LRBHO.

Thanks !  :)

I was pretty certain they would be good to go, but any feedback is great :)

All I use are PMags in my 762 OBR.  Work like a champ.  Never an issue
