Found this article and thought it was very informative. I have more than once heard supposed "authorities" claim that you should not shoot any bullet heavier than 150 grain in an M1.

I will only add that there have been tens of thousands of competitions, (out to 1,200 yards), shot with Garands loaded with LC, Federal, & Black Hills, 168 grain Match ammo over the years [check with the armourers at MCBQuantico!].
I am also aware that quite a few competitions using Garands were shot with the M72 Match 172 grain bulet, or its' modern equivalent, in recent years.

The biggest problem with garand gear testing is they used some of the weakest M2 ball as their baseline.

The late 60s M2 ball is notoriously underpowered.

Since lots of ammo is just barely too powerful according to them...I'd imagine a larger control sample may prove its not the danger the internet makes it out to be.

Oh... don't forget they are selling you a product and using their test data to support the reason you need to buy from them.
