Yes it is good to go.
Here is an e-mail from Springfield Armory to me on this subject.........
Springfield Armory Recommended ammo for our rifles chambered in .308
Any commercially produced, new in box .308 ammunition that meets the following requirements:
• Is a 147 to 180 grain bullet.
• Is full metal jacket (FMJ), hollow point (HP or BTHP), or ballistic tip type bullet.
• Hornady’s new superformance ammo is OK to shoot in the M1A but NOT recommended for the M1 Garand.
• Hornady tap ammo is better for the shorter barreled rifles.
• Black Hills re-manufactured ammo is ok to use.
You can also use SURPLUS 7.62X51 NATO ammo that meets the following requirements:
• Is clean and from sealed containers
• Is NATO spec. It will have a NATO spec mark on the case head and /or on the packaging that looks like a plus sign inside of a circle.
Ammunition NOT recommended for your rifle:
• Avoid using surplus ammo tha tis “loose” or “bulk” – is is inconsitant in size and can be reloads.
• Avoid using steel case ammo, it is VERY hard on your chamber and can reduce the life span of your rifle.
• Do not use “ light Magnum” type ammo.
• Do not use soft point (SP) ammo, the lead shavings can get into the action and jam it up.
• We do not recommend the use of any cast bullets.
For best accuracy we recommend:
• Federal Match or Black Hills match 168 or 175 grain
• Hornady Match/ custom 168 grain or Hornady TAP 110 or 168 grain.

Have a nice day!
