I do agree with Texasflyboy as I have shot a lot of FN 57-58 and it shoots
better than the Hornaday's M1 168 A-max, I have one unopened case of it
left but I don't shoot much anymore so it may last the rest of my life.
Just a thought, I have had many Match grade M1's over the years as well
as a custom built by Don McCoy. sad to say but my M1a's would outshoot
all of them.
I have found the SA barrels from 1951 and up to be as accurate as many
customs I have installed.
We had R Lee Earmey filming a Lock & Load series #9 a month ago and I talked
with him for hours about M1's and M1a's. He used four of my rifles for the show
and during our talk he stated he has four M1's and his best match rifle is a 2 MOA,
he also said his M1'A's will out shoot his M1's and the M1Ais his favorite rifle.
