I sent an email to Federal asking if they were aware of any problems of using Product Code AE308D .308 150 gr ammunition in M14 or M1A rifles. Their customer service is closed until 5 Jan.
I have been searching other forums and can find several posts on this ammo being used successfully in M14, M1A, FN FAL, AR-10, etc. Haven't found a single complaint about ammunition malfunctions or damage to firearms. Accuracy seems to be the only issue with many firearms shooting better with 168 gr ammunition. I will continue searching.
I normally shoot Federal 168 gr MatchKing through my bolt guns with excellent results. As I don't reload, I thought the 150 gr would be a cheaper alternative to get more range time. I was planning to use some in my M305, but now I am going to turn this into a test and document any problems encountered, shooting conditions. If available, I will pick up another can of the 150 gr.
