Most accuret and reliable M1A ammo? Federal Gold Medal Match
This is a discussion on Most accuret and reliable M1A ammo? Federal Gold Medal Match within the Ammunition forums, part of the M14 M1A Forum category; What grain feeds most reliably in an M1A? Is Federal Gold Medal Match the best ammo?
Im getting failures to feed with this deer shock ...
M80 ball. NATO surplus 144.5 - 147 gr ammunition. I have used Radway Green, FN Belgian, Portugese, and South African with no issues. The port pressure can be off with slow burning powders found in commercial ammo.
FGMM does work very well. I roll my own and use 155, 168, and 175 gr Nosler CC BTHP projectiles and IMR-4895 powder.
I don't know from your post if your asking about ammo in general or hunting ammo. If your looking for reliable feeding hunting ammo I used Remingtion 150grn or 165 grn PSP (pointed soft point) with no issues. Killed many a Deer with the 150's.
For factory ammo, I like the American Eagle (federal) 168gr 7.62x51 made specifically for the M1A rifle. It uses a 168gr HPBT projectile. It's very clean out of the box, it cycles and shoots very well through my standard model, also it can be found for about $15-$17 a box, cheaper in bulk. Also, has a nice headstamp (like it matters) and is reloadable. When i roll my own i use a Sierra 168gr. HPBT under 40.5 gr of IMR 4895. Which produces a extremely similar round with great accuracy.
+1 for No such thing....or M118 being the closest.
But you're looking for an easy way out of a much more complicated issue:
How to find and tune the best performing loads for your gun, for the conditions you usually encounter.
There are no easy shortcuts to load development:
What's your barrel twist/length....what bullet weight works best with what powder for your use ...and range limits.
I'm with you though.
Let us know what you find so we can avoid all the work too.
FWIW: Gold Medal Match usually works well for a lot guns, so if you've got the cash...go with it.
Some of the M80 military surplus ammunition just might shot as well in your rifle as the top of the line Gold Metal Match ammunition and cost a lot less per round. Some of the ammunition I have tested over the years below with scores. A full listing can be located here... Good luck with which one your rifle likes as good as candy...

This is truly the Land of Enchantment, this morning I watched as the March of the Tarantulas came on by the roads and fields this time of year on my way to the rifle range. Once again a great day on the range this morning, with party sunny/cloudy skies, Temp 67.1 - 70.9 °F, wind at 2.0- 3.5 MPH right out of the Northeast, humidity very high at 86%, elevation on range is 5,928 feet. I brought out my NM M1A.
Standard 100 yard range target, using my good eye.
This morning I started out with the American Eagle 7.62x51mm OTM specially designed for M1A's, it's 168 grain OTM ammunition.
Well the first string was a 198-6X with average of 0.989" MOA, (lot V21X596). Headstamp FC 10 7.62-M1A, bright shiny brass.
2nd grouping a little better with a 200-10X with average of 0.920" MOA, (Lot V21X596). Headstamp FC 10 7.62-M1A, bright shiny brass.
Then I shifted to the 220 yard targets, 10 out of 10 hits on the metal Gong. Headstamp FC 10 7.62-M1A, bright shiny brass.
Then I moved over onto the 560 yards target, using still the American Eagle 7.62x51mm OTM ammunition from '10, I hit 10 out of 10 on the metal Gongs.
I also like Radway Green M80. I just picked up two, 1k round cases (84 and 89 headstamp). Shoots great in my NM, but no M80 shoots super well from my Supermatch.
The 175 gr FGMM I bought from the CMP is fantastic. Shooting 1 - 2 MOA with irons at 200 yards. Anyone claiming a sub-MOA load without a scope is fulla BS. 10 shot groups anyway.
M852 has also been good to me, as is M118LR. I'll pass on the Special Ball (SB) variety.
168 and 175 gr handloads are impossible to beat for a given rifle. I start a separate development for each rifle and go up from 40.7 to 41.5 gr IMR-4895. Five groups at 0.2 gr intervals. I have a chrono and know what velocity they group well in (2600 - 2650 FPS). You'll know when you've hit the sweet spot. If you are too lazy to perform a proper development than you will never max out the accuracy.
