I had read my m&p 10 wouldn't like 7.62x51 although I have an abundance of lake city m80

from what I've read, .308win is higher pressure than 7.62x51 as opposed to 5.56x45 being higher pressure that .223rem..

so I was able to find a bunch of 147gr norma tactical for $.70/rd and it runs flawlessly

no idea if the m80 runs in the AR or not, haven't tried it yet myself..

good luck!
