I'm not a high volume poster but thought I'd share this one.
I bought a Springfield M1A about 6-7 years ago. I wasn't expecting great accuracy from this gun. Its not the match grade rifle just the standard rig.
As I'm a reloader I HAD to do some tinkering. I held to the very old Zedeker publishing that is known as the bible for all info regarding M1 Garand and M1A/M14. There is talk of not loading too hot of loads or too slow burning powders for fear of damaging the operating rod.
I broke the gun in using USA's factory 147 grain ammo. They seemed pretty spicy but didn't shoot all that well. I wanted a hunting load for deer and pigs so I thought a 150 grain ballistic tip would be about right.
After some experimenting I settled on 44 grains of IMR 4064. The groups were better but the brass would not always eject. A few years went on and I revisited IMR 4046 but this time with 125 grain bullets. Good groups and cycling of brass, but its not a very hard hitting round.
Now using the internet I found people talking about using the very versatile Varget. Turns out that when Zedeker did all of his work (I'm guessing in the 50's?) Varget wasn't even invented yet. 43.5 grains with Federal 210M primers has created a great grouping load for me anyway. Haven't run it through the Chrony yet but it shoots very well.
