Re: Hornady Match, Federal, or Remington Brass? .308
Of the three, I've had the most longevity from Hornady match and Winchester. I've used all of them in 308 bolt actions. Hornady is also very uniform and has case capacity similar to Winchester, cases weigh about 155 grains compared to 152 for Winchester. I think of Hornady Match brass as Winchester without out of spec throwaways.
Federal has the least capacity, similar in weight to Lake City at around 178 grains. FGMM once fired brass has been very uniform, but soft, in your M1A it won't matter. I got about 6 firings out of Federal before loose primer pockets on average, some less.
Remington brass was the shortest lasting for me at around 4 firings, and consistency is so-so, about like Winchester. Remington cases tended to weigh about 165 grains, putting them in the middle of the pack for capacity.
In my P-308 I use Lapua because I had it bought already from when I had a bolt gun, and it's on it's 4th loading cycle. They're all dinged up and the headstamps are smeared from the ejector(not pressure related, comes with the territory in AR's using Varget), but they're working fine. If I had the decision to make now, and I will soon I would go with either Hornady or Winchester based on cost vs how much time I wanted to spend on prep, for me it would lean toward Hornady. I've had some shitty luck with a few bags of Winchester brass in other calibers, they're kinda hit or miss I think. Rims that are too thick (a couple in a bag here and there), necks with uneven thickness(I don't neck turn and dont want to), etc. It's good brass as far as hardness and capacity, and if they would get some quality control I would probably switch to them exclusively for the price.
Edited to add that in an M1A, like my POF I suppose longevity isn't a big factor if you're throwing them out at 5 firings anyway. If it were me I would definitely skip Remington as I didn't get to 5 loadings with it. I would go with Hornady for the consistency alone, and will when the Lapua needs replacing.
Please note that my comments on case capacity are not scientific, as I have not actually filled them with water and measured their true capacity, but I think it stands to reason that lighter cases should have more capacity because they all have the same outer dimensions.
