I like PPU (Prvi white box, not the blue and white commercial stuff.) I have some LC, but I'm not happy with the quality... but that was from when Federal was running LC.

Dug up my notes on load info...for reference only. Please work up your own load.
Standard load...plenty accurate (1 to 1.25 moa)
40.0 IMR4895
CCI#34 primer
LC brass
Nosler 168CC 2.800COL

Accurate load (0.75 moa). Used it in a precision rifle match once. Ok at ringing steel out to 600 yards (full size ipsc).

I was going to mention a case gauge too. I started reloading for an M1a without one and had lots of trouble. Fired cases wouldn’t extract from the chamber. I got all kids of advice saying my load was too light until a gentleman on the M14 forum suggested I wasn’t sizing cases correctly. Sure enough I got a case gauge and my resized cases wouldn’t drop completely in.
The poor man's case gauge on the M1a is to strip the bolt (no extractor) and using finger pressure see if you can chamber a case and have the bolt freely rotate in to full battery. If the bolt hangs up somewhere, or won't cam into full lockup, your case is too long. That's assuming a clean chamber, and no problems elsewhere.
Yep. When I was having issues this “plunk test” was my first indication of sizing issues. It doesn’t make up for a case gauge though, as you can’t tell if you’ve gone too far. Also gauges can be kept at your bench and used occasionally while sizing brass.
